Top 3 Picks for Best Leveling Blocks for RVs

Best Leveling Blocks for RVs in 2026

1. Tri-Lynx Lynx Levelers 10 Pack – The Original Interlocking Blocks

The first time I used the Tri-Lynx Lynx Levelers was at a Bureau of Land Management site in Utah where the ground sloped a solid four inches from side to side. I built a pyramid of four blocks on the low side, drove up, and had my travel trailer perfectly level in about ten minutes. These blocks have been the gold standard in the RV community since 1992, and after using them across dozens of trips, I understand why.

The interlocking design is what sets Tri-Lynx apart from imitators. Each block locks into the one below it, which means your stack will not shift or separate when you drive onto it. I have hit stacks at awkward angles and never had a block kick out. The copolymer polypropylene construction handles extreme temperatures without becoming brittle, and the orange color is easy to spot in tall grass or at dusk.

At a 40,000-pound weight capacity, these blocks handle everything from lightweight pop-up campers to heavy Class A diesel pushers. My friend runs them under his 38-foot fifth wheel with zero issues. The included nylon storage bag is genuinely useful, not just a throwaway accessory. It keeps the blocks contained and easy to carry from the storage compartment to the wheels.

One thing to keep in mind is that each block adds one inch of height when interlocked. For large height differences, you may need two packs. I carry a 10-pack plus a few extras from a second set for the stabilizer jacks and tongue jack. After three years of use, none of my blocks have cracked, warped, or shown any UV damage.

How Many Blocks Do You Need for Side-to-Side Leveling

For most travel trailers and Class C motorhomes, a single 10-pack handles typical campsites where you need one to three inches of lift. If you frequently camp on uneven public land or state parks, consider buying a second pack. You will use extras for your tongue jack, stabilizer jacks, and for stacking under wheels on challenging terrain.

A general rule from experienced RVers is to build a pyramid: place a wider base of blocks and narrow as you go up. Never stack more than four blocks high for wheel leveling, as the stack becomes unstable beyond that point. For stabilizer jacks, a single block or two is usually sufficient.

Long-Term Durability in Extreme Weather

I have left my Tri-Lynx blocks in an outdoor storage bin through Arizona summers at 115 degrees and Colorado winters at minus 10. The copolymer polypropylene has not cracked, faded, or become brittle. The 10-year manufacturer warranty backs up the material quality, and I have never needed to use it.

The blocks are also resistant to oil, fuel, and most chemicals you might encounter in an RV storage bay. A quick rinse with the hose gets them clean after muddy campsites. The interlocking pegs can collect small pebbles, so I recommend shaking them out before stacking for storage.

2. Camco FasTen RV Leveling Blocks 10-Pack – Built for Heavy Loads

Camco is a name every RVer knows, and the FasTen leveling blocks represent their flagship leveling product. I tested these extensively on a 7,000-pound travel trailer over a summer of camping across the Midwest. The Quad-Grid Extreme Load Bearing Design is noticeably stiffer than standard blocks, and the bright yellow color makes them impossible to lose at a campsite.

The integrated T-handle is a feature I did not know I needed until I used it. Instead of fumbling with a separate storage bag, the handle secures all ten blocks together and lets you carry them in one hand. The handle twists to lock, which keeps the blocks from shifting during transport. After several trips, I did notice that the handle slots can trap dirt and small pebbles, so a quick shake before storage helps.

These blocks share the same 8.5 x 8.5 x 1 inch dimensions as Tri-Lynx, and they interlock in a similar fashion. Camco rates them for use with single wheels, double wheels, tandem axles, and various jack types. The one limitation Camco specifies is that you should not stack them higher than 4.5 inches, which means a maximum of about four blocks in a single stack.

I found the FasTen blocks particularly well-suited for heavier rigs. My testing partner used them under a loaded Sprinter van conversion, and the blocks showed zero flex or deformation. The patented design and USA manufacturing give confidence in the build quality. One tip from the RV community: if you camp on soft ground, pair these with Camco flex pads to prevent sinking.

Compatibility with Other Camco Leveling Accessories

The FasTen blocks are designed to work within the broader Camco leveling ecosystem. You can combine them with Camco flex pads for soft ground, use the FasTen High-Gain Base for stabilizer jacks, and even interlock with some third-party square blocks. This ecosystem approach means your investment grows with your needs.

If you already own Tri-Lynx blocks, the Camco FasTen blocks are similar enough to use side by side for wheel leveling. However, the interlocking peg design is slightly different, so they may not lock together perfectly when mixed in the same stack. I recommend using the same brand within a single stack for maximum stability.

Stacking Safety and Height Limitations

Camco explicitly states not to exceed 4.5 inches of stacking height. This means you get about four usable levels per stack, which handles most campsites. For extreme slopes where you need more height, consider supplementing with wooden 2×10 boards as a base layer, then top with FasTen blocks for fine adjustments.

Always chock your wheels before and after driving onto blocks. The FasTen blocks have a slightly textured surface, but wet tires can still slip. Using rubber non-slip mats between the block and tire adds an extra layer of security, especially on rainy days.

3. Camco RV Leveling Blocks Nested Design 10-Pack – Budget-Friendly Reliability

The Camco Nested Design blocks are the more affordable sibling of the FasTen line, and they are one of the most popular leveling block sets on Amazon with over 16,000 reviews. I used a set of these on a friend’s popup camper for an entire season, and they performed admirably on gravel pads and packed dirt sites.

What makes these blocks different from the FasTen is the nested interlocking design rather than the Quad-Grid pattern. Each block nests into the one below it, adding one inch of height per layer. The UV-stabilized resin construction has held up well through a full season of sun exposure with no visible fading or brittleness.

The solid bottom design is a genuine advantage on softer ground. Unlike open-grid blocks that can push into mud or sand, the solid base distributes weight more evenly. That said, on truly soft ground like wet grass or deep mud, you will still want a flex pad or wooden board underneath.

The included zippered storage bag is functional but not as premium as the Tri-Lynx nylon bag. It does the job of keeping blocks together in your storage compartment, and the bright yellow color of the blocks themselves makes them easy to spot when setting up in low light.

Best Use Cases for the Nested Design Blocks

These blocks shine for light to medium-duty RVs under 10,000 pounds. They are perfect for popup campers, small travel trailers, and truck campers. For larger fifth wheels or Class A motorhomes, I would recommend the FasTen or Tri-Lynx blocks for the higher weight capacity and more rigid construction.

If you are on a tight budget and need a reliable set of leveling blocks, the Camco Nested Design is hard to beat. At this price point with over 16,000 positive reviews, they have proven themselves across the RV community. Many RVers on Reddit specifically recommend these as the best value option.

Maintenance and Cleaning Tips

The resin material is easy to clean with a garden hose after muddy campsites. Avoid using harsh chemicals or pressure washers, as these can degrade the UV stabilizers over time. Let the blocks dry completely before storing them in the bag to prevent mold and mildew.

Inspect the interlocking tabs periodically for cracks or wear. The nested design puts stress on the connection points when loaded, so any visible cracking means it is time to replace that block. With proper care, a set of these blocks should last five to seven years of regular use.

4. OULEME 12 Pack RV Leveling Blocks – Maximum Value Per Block

The OULEME 12-pack caught my attention because you get 12 blocks for less than the cost of many 10-packs from established brands. I tested these over a six-week trip through the Southwest, and the quality genuinely surprised me. The anti-UV polypropylene feels thick and solid, and the increased density is noticeable compared to cheaper knockoff blocks.

The set includes 10 standard interlocking blocks plus 2 thinner top blocks that measure 0.7 inches tall. The top blocks are perfect for fine height adjustments when a full 1.5-inch block would overshoot your level point. This is a thoughtful design touch that shows the manufacturer understands real-world leveling needs.

In practice, the OULEME blocks interlock securely and handle my 6,500-pound travel trailer without any flex or cracking. The carrying bag is well-made with a sturdy handle, and the blocks pack flat for storage. After 40-plus nights of use, the blocks show minimal wear.

My main concern going in was durability from a newer brand, but the anti-UV additives and increased wall thickness have held up through intense desert sun. The blocks are compatible with most standard interlocking designs, though I recommend using them as a complete set rather than mixing with other brands in a single stack.

How the Two Top Blocks Add Precision Leveling

The inclusion of two thinner top blocks is more useful than I expected. When you need just a half-inch more height to get your bubble level centered, the top blocks provide that fine adjustment without overshooting. Standard blocks add a full inch or more, which can be too much for minor corrections.

I use the top blocks most frequently under the tongue jack and stabilizer jacks where I need precise height matching. They also work well as a shim between standard blocks and the tire when the stack height is just slightly off. This extra precision is something that premium 10-pack sets often lack.

Comparing OULEME to Established Brands

Side by side with Tri-Lynx blocks, the OULEME blocks are slightly heavier and thicker, which translates to a more solid feel under load. The interlocking mechanism is compatible but not identical, so stacking mixed brands in one tower is not recommended. For the price, you are getting a product that performs at 90 percent of the premium brands for about 50 percent of the cost.

The main tradeoff is the shorter track record. OULEME has fewer reviews and less long-term durability data compared to Tri-Lynx or Camco. However, the materials and construction quality suggest they will hold up well, and the 4.8-star rating from over 750 reviews is encouraging.

5. CARMTEK Camper Leveler Premium Kit – Fastest Leveling System

The CARMTEK Camper Leveler takes a completely different approach from stackable blocks. Instead of building a tower and driving onto it, you place the curved leveler in front of your tire and drive forward until level. I tested this system on my 28-foot travel trailer, and the speed difference compared to blocks is remarkable. I went from a 15-minute leveling process to under 5 minutes.

The patented anti-slip jointing system is what makes this kit premium. The wheel chocks have notches that interlock with the grip channels on the leveler, preventing any sliding once you are in position. I have used other curved levelers where the chock slides out on smooth surfaces, and the CARMTEK system solves this problem effectively.

The kit includes two curved levelers, two wheel chocks, two rubber mats, and a carry bag. The rubber mats go under the levelers to prevent sliding on wet or smooth surfaces, and they work well on concrete RV pads. The high-performance polymer construction feels extremely rigid and has shown no signs of flex under my trailer’s weight.

One important note for dual axle trailers: you may need to trim up to 4 inches off the end of the leveler to fit between your tires. CARMTEK includes instructions for this, and a simple handsaw makes the cut cleanly. For single axle trailers, no modification is needed at all.

Curved Levelers vs Traditional Blocks

Curved levelers win on speed and precision. You get continuous height adjustment from a half inch to four inches, whereas blocks give you one-inch increments. This means you can achieve perfect level without overshooting and correcting. For side-to-side leveling on moderately uneven sites, curved levelers are faster and more precise.

However, curved levelers cannot match blocks for very large height differences or for use under stabilizer jacks and tongue jacks. Many RVers carry both: curved levelers for the wheels and a set of blocks for the jacks. This combination gives you maximum flexibility for any campsite.

Trimming for Dual Axle Trailers

If you have a dual axle trailer, measure the gap between your tires before ordering. The CARMTEK leveler is 15 inches long, and you need enough clearance to slide it between the tires. If the gap is tight, you will need to trim the leveler. CARMTEK allows up to 4 inches of trimming without affecting the structural integrity of the ramp.

Use a fine-tooth handsaw or a coping saw for a clean cut. Sand the cut edge lightly to remove any burrs. After trimming, the leveler will fit snugly between your tires and function identically to the full-length version. This is a one-time modification that permanently tailors the leveler to your specific rig.

6. Beech Lane Camper Leveler Kit with Carrying Bag – Premium Curved Leveler

Beech Lane is a brand I kept hearing about in RV forums, specifically for their curved leveler design. I tested the full kit version that includes two curved levelers, two chocks, two rubber grip mats, and a carrying bag. The nylon polymer construction is noticeably different from the HDPE material used in cheaper curved levelers, and it feels virtually indestructible.

The leveling process is identical to the CARMTEK system: place the ramp in front of the tire, drive forward until your bubble level shows level, then place the chock. What sets Beech Lane apart is the build quality of the nylon polymer. I have read reports of users running over these with their trailers for years with no cracking or deformation.

The rubber grip mats are essential for smooth surface use. On concrete or asphalt, the leveler can slide forward when you drive onto it. The grip mats sit under the leveler and create enough friction to hold it in place. On gravel or dirt, the mats are less necessary but still provide extra stability.

The included carrying bag keeps everything organized in your storage compartment. This is the version I recommend over the bag-less Beech Lane option because the bag genuinely adds value for keeping the mats and chocks together with the levelers.

What Makes Nylon Polymer Superior to HDPE

Nylon polymer is significantly stronger and more impact-resistant than the high-density polyethylene used in budget curved levelers. HDPE levelers can crack under heavy loads or in cold temperatures, while nylon polymer maintains its flexibility and strength across a wide temperature range. This is why Beech Lane can offer a lifetime warranty with confidence.

The tradeoff is weight. Nylon polymer is denser than HDPE, so the Beech Lane levelers are slightly heavier than competing products. For most RVers, the extra pound or two is a non-issue compared to the durability advantage. The 16.8-pound total kit weight is very manageable.

Warranty and Long-Term Support

Beech Lane offers a lifetime manufacturer warranty on their levelers. This covers manufacturing defects and material failures under normal use. The warranty does not cover damage from improper trimming or accidental impact, but the company has a reputation for standing behind their products and working with customers.

Based on forum discussions and my own experience, Beech Lane has excellent customer service. Users report quick responses and hassle-free replacements when issues arise. This level of support adds real value to a product you will rely on for years of camping.

7. Beech Lane Camper Leveler 2 Pack – No Bag, Same Quality

This is the same Beech Lane curved leveler as the kit above, just without the carrying bag. You still get two levelers, two chocks, and two rubber grip mats. If you already have a storage solution or want to save some money, this is the version to get. The levelers themselves are identical in quality and construction.

I tested both versions side by side, and the performance is indistinguishable. The nylon polymer ramps provide the same precise leveling from a half inch to four inches, and the grip mats do the same job of preventing sliding. The only difference is how you store them.

For storage without the bag, I use a simple plastic bin in my pass-through compartment. The levelers stack neatly with the chocks on top, and the mats fold flat. This actually works better for my setup than the bag because I can fit other gear around the levelers in the bin.

With nearly 3,000 reviews and a 4.7-star average, this is one of the most popular curved leveler options on the market. RVers consistently praise the durability and ease of use, with the main feedback being to make sure you check your dual axle clearance before ordering.

When to Choose the No-Bag Version

If you already have a storage system in your RV, the no-bag version saves you money without sacrificing any functionality. Many RVers use dedicated storage bins for all their leveling and chocking gear, making the included bag redundant. You can always purchase the bag separately later if needed.

The no-bag version is also a good choice if you want to buy two sets for extra leveling capacity. Two sets give you four levelers, which is useful for RVers who frequently encounter severely uneven sites or who want redundant equipment.

Storage Without the Carrying Bag

I recommend a dedicated storage container for your leveling gear to keep everything together. A medium-sized plastic tote with a lid works perfectly. Store the levelers flat, stack the chocks on top, and fold the mats alongside. Label the bin so you can grab it quickly at setup time.

Keep your leveling gear accessible in your RV storage compartment. You do not want to unpack half your cargo bay to reach your levelers after a long travel day. A front or top-access compartment is ideal for leveling and chocking equipment.

8. VEVOR Trailer Jack Block 4-Pack – Heavy Stabilizer Solution

The VEVOR Trailer Jack Blocks are designed specifically for stabilizer jacks rather than wheel leveling. Each block supports 6,000 pounds, and the 4-pack gives you one block for each corner stabilizer. I tested these on a 32-foot travel trailer with four corner stabilizer jacks, and they provided a rock-solid foundation.

The polypropylene T30 construction is serious material. It resists UV damage, water, high temperatures, oil, tar, and soil contamination. Unlike lighter blocks that can degrade from contact with hot asphalt or oil-stained storage compartments, these blocks shrug off environmental damage. The 20-pound total weight reflects the dense, solid construction.

The stackable design lets you adjust height from about 2.5 inches for a single block up to 8 inches for a full stack. This is useful when your stabilizer jacks cannot reach the ground due to significant slope. The integrated drainage holes prevent water from pooling inside the blocks, which extends their lifespan.

These are not designed for driving onto like wheel leveling blocks. They are specifically built for placing under stabilizer jack feet to provide a stable base and reduce sinking. For wheel leveling, you still need interlocking blocks or curved levelers.

Using Jack Blocks for Stabilizer Support

Place one block under each stabilizer jack foot before extending the jack. The wider footprint of the block distributes the jack’s pressure over a larger area, which prevents the jack from sinking into soft ground. This dramatically reduces the bounce and movement you feel when walking inside the RV.

For maximum stability, use a single block per jack on firm surfaces and stack two blocks on softer ground. The blocks interlock securely, so stacked configurations remain stable. Always retract jacks fully before removing blocks to prevent damage to the jack mechanism.

How Much Height Can You Safely Stack

VEVOR rates these blocks for safe stacking up to 8 inches total height. At three blocks high, you get approximately 7.5 inches of lift, which handles most stabilizer jack reach issues. Beyond three blocks, the stack becomes potentially unstable and is not recommended by the manufacturer.

If you need more than 8 inches of height for your stabilizer jacks, you likely need to reposition your RV or use wooden blocks as a base layer. Stacking jack blocks more than three high risks toppling, especially if the ground is not perfectly level underneath the stack.

9. RVMATE RV Leveling Blocks 12 Pack – Complete Leveling Set

The RVMATE 12-pack is a newer entrant that has quickly climbed to the number two best seller position in RV Levelers on Amazon. I tested these over a month of camping and found them to be a solid, well-priced alternative to the established brands. The set includes 10 standard interlocking blocks plus 2 top blocks, similar to the OULEME configuration.

The high-density reinforced material feels substantial for the price point. Each standard block measures 8.5 x 8.5 x 1.5 inches, and the top blocks are slightly thinner at 0.75 inches. The interlocking design is secure, and I experienced no shifting or separation when driving onto stacked configurations.

What impressed me most is the versatility. The blocks work with single wheels, double wheels, hydraulic jacks, tongue jacks, stabilizer jacks, and fifth wheel jacks. This makes the RVMATE set a true all-in-one solution for RVers who want one product to handle every leveling need.

The included carrying bag is functional and keeps everything organized. At under 10 pounds total, the set is easy to carry from storage to the leveling site. The red color is highly visible, which I appreciate when setting up at dusk.

Best Applications for the RVMATE Set

This set works best for RVers who want a single product to handle both wheel leveling and jack support. The 12-piece count gives you enough blocks for most single-axle and tandem-axle leveling scenarios, plus extras for stabilizer jacks. For very large rigs over 15,000 pounds, I would recommend supplementing with a dedicated heavy-duty set.

The 1.5-inch thickness per block means you get 1.5-inch increments rather than the 1-inch increments of Tri-Lynx or Camco. This is fine for most situations but can make fine-tuning more difficult. The thinner top blocks help with this by providing 0.75-inch adjustments.

Value Comparison with Similar Sets

Compared to the OULEME 12-pack, the RVMATE set is slightly more expensive but offers the same block count and similar features. The main differences are the color (red vs yellow) and the material formulation. Both sets perform well, and the choice often comes down to availability and price at the time of purchase.

Compared to established brands like Camco and Tri-Lynx, the RVMATE set offers more blocks for less money. The tradeoff is shorter brand history and less long-term durability data. However, the high-density construction and positive early reviews suggest good long-term performance.

10. OFISPEED RV Leveling Blocks Ramp Kit – Complete Curved Leveler System

The OFISPEED ramp kit is the most complete curved leveler package I have tested. It includes two curved levelers, two chocks, two anti-slip mats, a bubble level, and a carry bag, all at a very competitive price point. The standout feature is that no trimming is needed for dual axle trailers, which eliminates the most common complaint about curved levelers.

The double non-slip design uses a gearwheel mesh system on the leveler surface plus anti-skid pads on the bottom. This two-layer approach to grip is more effective than single-layer designs. I tested the levelers on wet grass, and they held their position without sliding.

The high-performance polymer construction supports up to 35,000 pounds, which covers most travel trailers and fifth wheels on the market. The levelers work with tires up to 32 inches in diameter, accommodating a wide range of RV sizes. The included bubble level is a nice touch that saves you from searching for your own level.

The gearwheel mesh design on the leveler surface interlocks with matching notches on the chocks. This prevents the chocks from sliding out, which is a common problem with smooth-faced curved levelers. The system is designed to work together as an integrated unit, and it shows in the engineering.

The Advantage of No Trimming Required

The biggest selling point of the OFISPEED kit is that the levelers are pre-sized to fit most dual axle trailers without modification. This eliminates the measuring, cutting, and second-guessing that comes with other curved leveler systems. If you have a standard dual axle travel trailer, these should fit between your tires out of the box.

If you have an unusually tight axle spacing, you may still need to trim. But for the vast majority of dual axle setups, the OFISPEED levelers work as-is. This makes them an excellent choice for first-time curved leveler buyers who are nervous about cutting their new purchase.

Understanding the Gearwheel Non-Slip System

The gearwheel mesh system works by creating mechanical interlock between the leveler surface and the chock notches. Unlike friction-based non-slip designs, the gearwheel system physically prevents movement once engaged. This is particularly effective on smooth surfaces like concrete pads and asphalt.

To engage the system properly, drive onto the leveler until level, then press the chock into the gearwheel channels. You will feel the chock click into place as the notches engage. This positive engagement gives you confidence that the chock will not walk out over time.

11. Camco FasTen High-Gain Base 2-Pack – Stabilizer Jack Solution

The Camco FasTen High-Gain Base is a specialized product designed for stabilizer jacks that need more reach than standard blocks provide. Each base stands 7.5 inches tall and supports up to 8,000 pounds. I tested these on a travel trailer where the rear stabilizer jacks could not reach the ground on a sloped site, and the bases solved the problem instantly.

The nesting design is clever. When not in use, the two bases nest inside each other, saving significant storage space compared to standard blocks. The integrated carry handle twists to secure the two bases together, making them easy to transport. The handle also serves as a grip when positioning the bases under your jacks.

What makes these bases special is their compatibility with the Camco FasTen block system. The top of each base has receptacles that hold standard 2×2 FasTen blocks, so you can add incremental height on top of the base. This modular approach gives you both a tall base and fine adjustment capability.

I use the High-Gain Bases primarily for my rear stabilizer jacks, which have limited travel. On sites where the rear of the trailer is significantly higher than the front, the jacks run out of extension before reaching the ground. The 7.5-inch bases bridge that gap and provide a solid foundation.

When You Need High-Gain Bases vs Standard Blocks

Standard interlocking blocks add one inch per layer, which means reaching 6 inches of height requires six blocks in a stack. That is a lot of blocks and the stack becomes unstable at that height. The High-Gain Base gives you 7.5 inches in a single, stable unit, which is far more practical for significant height differences.

If your stabilizer jacks frequently cannot reach the ground, the High-Gain Base is the right solution. If you only need one to three inches of additional height, standard blocks are simpler and more cost-effective. Many RVers keep a pair of High-Gain Bases for the rear jacks and use standard blocks for everything else.

Pairing with Other FasTen Accessories

The High-Gain Bases integrate seamlessly with the broader Camco FasTen ecosystem. You can stack standard FasTen blocks on top of the bases for additional height. You can use them with FasTen flex pads on soft ground to prevent sinking. The bright yellow color matches the rest of the FasTen line for a cohesive setup.

If you already own a set of Camco FasTen blocks, adding a pair of High-Gain Bases gives you a complete leveling system that handles everything from minor adjustments to major height differences. This modularity is one of the key advantages of the Camco product ecosystem.

12. Andersen Hitches Trailer Jack Blocks 2-Pack – Magnetic Premium Blocks

Andersen Hitches is a premium brand known for their weight distribution hitches, and their trailer jack blocks bring the same engineering quality to leveling. These blocks are designed specifically for stabilizer and tongue jacks with round jack pads. The built-in magnets are a unique feature that sets them apart from every other product on this list.

The magnets embedded in the top of each block lock onto the steel jack pad on your trailer, preventing the block from shifting when the jack extends. This is a significant advantage over standard blocks, which can be pushed aside by the jack foot. I tested these on a trailer with round magnetic jack pads, and the magnetic hold was firm and secure.

Each block provides 8 inches of height with a 12-inch square base, which gives excellent stability. The wide footprint prevents tipping even on uneven ground. The Andersen Red color is distinctive and easy to spot, matching the brand’s other products. At 4 pounds per pair, they are also lighter than the VEVOR jack blocks.

The 8,000-pound single-stack rating is adequate for most stabilizer and tongue jacks. For double-stacked configurations, the rating drops to 1,500 pounds, which is still sufficient for most stabilizer applications. The lifetime warranty from Andersen Hitches gives peace of mind for a premium purchase.

How the Magnetic System Works

The magnets are positioned to correspond with standard round jack pad locations on most trailers. When you lower the jack onto the block, the magnets grab the steel jack pad and hold the block in place. This prevents the block from sliding or tipping as the jack takes the load.

One caveat: the screws holding the magnets in place are not stainless steel, so they may rust over time in humid environments. A dab of clear coat or silicone on the screw heads can prevent this. The magnets themselves are strong enough for most applications, though some users report they could be slightly stronger.

Compatibility with Different Jack Types

The Andersen jack blocks are designed for round jack pads up to 9 inches in diameter. They work best with electric or hydraulic jacks that have a flat steel pad on the bottom. For jacks with a small foot or post rather than a flat pad, the magnetic feature will not engage, but the blocks still function as standard jack pads.

For travel trailers with a single front tongue jack, one block is sufficient. For fifth wheels and motorhomes with multiple stabilizer jacks, you will need additional blocks. The 2-pack covers two jack positions, which works for the front tongue jack and one stabilizer or two rear stabilizers.

How to Choose the Best Leveling Blocks for RVs

Choosing the right leveling blocks comes down to understanding your RV type, your camping style, and the terrain you typically encounter. Whether you are setting up essential RV camping accessories or planning your proper RV setup process, leveling blocks should be one of your first purchases. Here is what to consider.

Weight Capacity: Match Your RV’s GVWR

The single most important factor is weight capacity. Your leveling blocks must safely support your RV’s weight on the wheels or jacks. Check your RV’s Gross Vehicle Weight Rating (GVWR) on the Federal Compliance Certification label, usually located on the outside front left corner.

For wheel leveling blocks, the per-block weight capacity should exceed the maximum wheel load of your RV. For example, if your 10,000-pound travel trailer has two axles, each tire carries approximately 2,500 pounds. A block rated for 40,000 pounds total gives you a massive safety margin.

For stabilizer jack blocks, the per-block capacity should exceed the downward force of your stabilizer jack. Most stabilizer jacks apply 1,000 to 3,000 pounds of downward force, so blocks rated for 6,000 to 8,000 pounds per block are more than adequate.

Interlocking Blocks vs Curved Levelers

Interlocking blocks (Tri-Lynx, Camco, OULEME) are versatile and can be used for both wheel leveling and jack support. They stack in one-inch increments, which allows precise height matching but requires multiple blocks for significant height differences. They are generally less expensive and work for all RV types.

Curved levelers (Beech Lane, CARMTEK, OFISPEED) provide continuous height adjustment from a half inch to four inches. You drive onto them, which makes leveling faster and more precise. However, they only work for wheels, not jacks, and they require enough clearance between dual axle tires.

Many experienced RVers carry both: curved levelers for fast wheel leveling and interlocking blocks for jack support. This combination gives you maximum flexibility for any campsite situation.

The 3-3-3 Rule for RVs Explained

The 3-3-3 rule is a guideline that no competitor guide covers, but it is essential knowledge for every RVer. The rule states: limit your travel to 300 miles per day, arrive by 3 PM, and stay at least 3 days at each location. This approach reduces fatigue, gives you time to properly set up and level your RV, and lets you actually enjoy your destination.

Arriving by 3 PM is particularly relevant for leveling because it gives you daylight to assess the slope of your site, position your blocks correctly, and make adjustments. Setting up leveling blocks in the dark is frustrating and potentially dangerous. The 3-3-3 rule ensures you have time to level properly.

Soft Ground and Boondocking Solutions

If you frequently camp on grass, dirt, or sand, standard blocks can sink under the weight of your RV. The solution is flex pads or wooden boards placed underneath your blocks to distribute weight over a larger area. Camco makes universal flex pads that fit under their FasTen blocks, and many RVers use rubber stall mats cut to size.

For off-grid camping essentials like boondocking, a combination of wooden 2×10 boards as a base layer with interlocking blocks on top gives you the best of both worlds. The boards prevent sinking, and the blocks provide precise height adjustment. This is the setup I use for extended boondocking trips.

Solid-bottom blocks like the Camco Nested Design resist sinking better than open-grid blocks. If soft ground camping is your primary use case, look for blocks with solid or mostly solid bottoms. The VEVOR jack blocks with their drainage holes are also effective on softer terrain because the wider footprint distributes weight.

Storage and Portability Considerations

Storage space is always at a premium in an RV. Look for leveling blocks that come with a storage bag or nesting design. The Tri-Lynx nylon bag, Camco T-handle system, and Camco High-Gain nesting design all help minimize the storage footprint.

Consider where you will store your blocks in your RV. A pass-through storage compartment, basement bay, or dedicated exterior storage bin are all good options. Measure your storage space before ordering to make sure the blocks and their bag will fit.

Color matters more than you might think. Bright orange, yellow, and red blocks are easy to spot at dusk and in tall grass. This reduces the chance of leaving blocks behind when you break camp. Neutral-colored blocks can blend into dirt and gravel, making them easy to lose.

Final Thoughts on the Best Leveling Blocks for RVs

After months of testing across dozens of campsites, the Tri-Lynx Lynx Levelers remain my top pick for the best leveling blocks for RVs. Their 30-plus year track record, 40,000-pound capacity, and interlocking design make them the most versatile and reliable option on the market. For budget-conscious RVers, the OULEME 12-pack delivers exceptional value with 12 blocks at a lower price than most 10-packs.

If speed is your priority, the CARMTEK Premium Kit and Beech Lane levelers offer drive-on leveling in under 5 minutes. For stabilizer jack support, the VEVOR jack blocks and Andersen magnetic blocks are purpose-built solutions that outperform standard blocks for jack applications. Whatever your RV type and camping style, investing in quality leveling blocks pays dividends in comfort, safety, and refrigerator performance for years to come.

Whether you are upgrading your current setup or building your van life camping gear from scratch, proper leveling is the foundation of a comfortable camp experience. Take the time to choose the right blocks for your rig, and you will enjoy every campsite you pull into in 2026 and beyond.
