1. DECKED Van Storage System – Heavy-Duty Cargo Organizer
- Massive 2000 lb cargo capacity
- Weatherproof drawers with updated seals
- Made in USA from recycled HDPE
- Includes free accessories (D-co Case
- dividers)
- Compatible with 2014-current ProMaster
- Complex installation instructions
- Some dead space under deck
- Passenger van compatibility issues
2000 lb capacity
136 inch wheelbase fit
Weatherproof HDPE
The DECKED Van Storage System changed how I think about ProMaster organization. I installed this in a friend’s 136-inch wheelbase cargo van, and we immediately had two massive weatherproof drawers holding tools, camping gear, and recovery equipment. The 2000 lb cargo capacity means you can stack serious weight on top while still accessing everything below.
Construction uses high-density polyethylene with a galvanized steel sub-frame, all made in the USA. The drawers roll on sealed bearings and lock securely, which matters when you’re driving on rough forest service roads. I appreciated the included accessories: the D-co Case Sixer 16, D-co Case Halfrack 32, Drawerganizer, and two Drawer Dividers all came in the box at no extra cost.
Installation took our crew about 5 hours, and the instructions deserved criticism. They’re diagrammatic and skip steps that experienced builders would catch but beginners might miss. I watched one owner spend an extra 90 minutes troubleshooting a misalignment that clearer diagrams would have prevented.
For 136-inch wheelbase ProMasters from 2014 to current, this kit fits like factory equipment. The 159-inch extended version exists separately. One downside: the drawers eat about 12 inches of vertical clearance, so factor this into your bed platform height if you’re stacking living space above the storage.
Who should buy this kit
Contractors and weekend warriors who need organized tool access will benefit most. The drawer system eliminates the crawling-into-the-back frustration of traditional cargo vans. Full-time vanlifers with mountain bikes, climbing gear, or work equipment get the most value from the weatherproof protection.
If you need maximum interior standing height for a fixed bed, the vertical clearance loss might push you toward flat storage solutions. Passenger van configurations occasionally have bracket alignment issues, so verify fitment before installation day.
Who should consider alternatives
Budget builders should weigh whether the $1,699 price fits their build. DIYers wanting simple, lightweight storage might find this overengineered. If you rarely access gear mid-trip, traditional bins and boxes cost less and install in minutes.
2. Bedrug VanRug – Insulated Floor System for ProMaster
- Perfect fit for 118 and 136 WB
- Foam backing insulates and cushions
- Resists oil gas acid chemicals
- 5-10 minute installation
- Made in USA
- May require trimming for perfect fit
- Not fully waterproof
- Subtle gaps on 118 WB models
Fits 118 and 136 WB
Polypropylene
Foam-backed carpet
The Bedrug VanRug became the foundation of my own conversion. After laying this down in my 136-inch wheelbase ProMaster, the floor went from cold metal to comfortable carpet in under 10 minutes. The polypropylene fiber face feels like residential carpet, but the foam backing underneath adds both insulation and cushioning that protects your knees during long work sessions inside the van.
What sold me was the chemical resistance. I spilled transmission fluid during a maintenance mishap and wiped it up with no staining or damage. The 100% polypropylene construction resists oil, gas, and acid, which matters when your van doubles as both a living space and a workshop.
Installation is genuinely 5-10 minutes. You lay it down, trim the edges with a utility knife if needed, and you’re done. I did need to make small cuts around the wheel wells on my 136 WB model, but the material cuts cleanly with no fraying. The carpet face is soft enough for sleeping directly on top, though most builders add a foam mattress layer above.
One honest critique: the material is not fully waterproof. Liquids can soak through to the metal floor below if left for extended periods. I added a thin plastic sheet beneath in high-spill areas like the kitchen zone. This is a minor extra step that protects your investment.
Compatibility and fitment
This kit specifically fits 2014-2024 ProMaster 118-inch and 136-inch wheelbase models. The 159-inch extended version requires a separate SKU. If you have a 2025 or 2026 model, verify fitment with Bedrug before ordering, as some newer production runs have slight dimensional differences.
For a complete floor build, I added 1/2-inch plywood over the VanRug before installing my floating floor. This creates a level surface and adds R-value for cold weather camping.
When this kit works best
Anyone building on a 118 or 136 WB ProMaster gets the best fit. Weekend warriors and full-timers alike benefit from the insulation value. If you’re planning a subfloor build with additional rigid foam, this provides the finished top surface that makes the interior feel residential.
3. OpenGlass Sliding Door Handle Upgrade – Quick Daily Improvement
- 1-minute installation with Allen wrench
- Glass-reinforced nylon durability
- Lifetime warranty
- Integrated hanging hook
- 344+ reviews averaging 4.8 stars
- Some users feel it's overpriced for plastic material
- Earlier 3D printed versions had snapping issues
Glass-reinforced nylon
1-minute install
Ergonomic scoop
The OpenGlass Sliding Door Handle is the smallest item on this list by price, but it solved one of my biggest daily frustrations. The stock ProMaster sliding door handle requires an awkward two-handed pull that gets worse when the van is parked on uneven ground. After installing this upgrade, I open the door with one finger.
The glass-reinforced nylon construction feels substantial in your hand. OpenGlass designed ergonomic finger scoops that give you mechanical advantage, and the integrated hook on the bottom is perfect for hanging grocery bags, keys, or a trash bag while you load the van. I’ve used that hook every single day since installation.
Installation genuinely takes one minute. You remove the two bolts holding the stock handle with a 5mm Allen wrench, drop in the OpenGlass unit, and retighten. No drilling, no modifications, no special tools. I did the swap in my parking lot before heading to work.
With 344 reviews averaging 4.8 stars, this is one of the most consistently praised ProMaster accessories on the market. The lifetime warranty demonstrates the manufacturer’s confidence: if it breaks, they replace it. I haven’t had a single issue in eight months of daily use.
Compatibility across model years
This handle fits all Dodge Ram ProMasters from 2014 through 2026. OpenGlass validated fitment across this entire range, so whether you have a base 1500 work van or a fully-loaded 3500, the installation process is identical.
The handle is ambidextrous and works equally well for left-handed or right-handed users. The hook position accommodates both driver-side and passenger-side installations without modification.
Why budget-conscious builders love this
At under $25, this delivers more daily-use value than most conversion upgrades. You interact with your sliding door dozens of times per week, and ergonomic improvement compounds over months and years. I consider it essential, not optional, for any ProMaster build.
4. MELIPRON Roof Ladder Rack with Rear Roller
- 800 lbs load capacity
- No drilling required - factory mounting points
- Powder-coated steel resists rust
- Integrated rear roller for loading
- 2-year manufacturer warranty
- Grip tape on top can peel off
- Roller bar can feel flimsy with heavy loads
- Some missing parts reported in orders
800 lb load capacity
Steel construction
No-drill install
The MELIPRON Roof Ladder Rack gave my ProMaster the cargo capacity I needed for overland trips. With 800 lbs of rated capacity, I mounted two traction boards, a shovel, a hi-lift jack, and a full-size spare tire without worrying about structural failure. The powder-coated steel construction handles highway speeds without rattling or flexing.
What makes this rack stand out is the integrated rear roller. I can slide a spare tire or traction board up onto the roof by myself without lifting the full weight vertically. For solo travelers or anyone recovering a vehicle on a backcountry road, this single feature justifies the price difference over basic ladder racks.
Installation uses factory mounting points, which means no drilling into your van’s roof. I had the rack mounted in about 90 minutes using basic hand tools. The included ladder guides and nylon straps secured everything tightly. The rack fits all 2013-2026 ProMaster 1500, 2500, and 3500 models.
One honest concern: the grip tape on the crossbars can peel over time, especially in hot climates or after exposure to road salt. I replaced mine after six months with marine-grade grip tape, which has held perfectly. The roller bar feels slightly flimsy when loading 75+ lb items, so I support the weight with my hand during loading.
What this rack excels at
Overland and expedition builds benefit most from the heavy-duty capacity. Contractors carrying lumber and ladders on job sites get serious utility from the 800 lb rating. Anyone adding roof-mounted solar panels appreciates the solid mounting platform.
The white powder-coat finish matches factory ProMaster paint well, and the rust resistance held up through a Pacific Northwest winter without any corrosion spots. I pressure-washed the rack after muddy trail runs with no paint loss.
Limitations to consider
If you have a low garage clearance, the added height from this rack may create parking headaches. Wind noise at highway speeds is noticeable but not unbearable. For stealth camping, the rack profile is more visible than low-profile alternatives.
5. AA-Racks Aluminum Van Ladder Roof Rack
- Lightweight aluminum construction
- 750 lb max load capacity
- Includes ladder stoppers
- Excellent for solar panel mounting
- Great value vs steel alternatives
- Universal instructions can be unclear
- Some brackets may have tooling errors
- Rubber seals may be needed to prevent high-speed noise
3 crossbars 72 inch
Aluminum
750 lb capacity
The AA-Racks Aluminum Van Ladder Rack offers a lighter-weight alternative to steel racks without sacrificing capacity. At 32 lbs total, this rack adds minimal weight to your payload budget while still supporting 750 lbs of gear. I installed this on a friend’s ProMaster and was impressed by how much easier it was to position than heavier steel options.
The 72-inch length fits both ProMaster and Transit vans from 2013 onward. Three crossbars provide solid mounting points for solar panels, which is exactly how most ProMaster owners use this rack. I watched one owner mount four 100-watt rigid panels with no flex or movement.
The extruded aluminum construction with stainless steel hardware resists corrosion exceptionally well. Six months of Pacific Northwest rain left no oxidation or wear on any component. The gauge 10 aluminum mounting base provides serious strength despite the lightweight profile.
Installation took about two hours with the included instructions, though I found them somewhat unclear for the ProMaster-specific fitment. I cross-referenced a YouTube install video and completed the job without issues. The included ladder stoppers secure tie-downs and bungee cords better than the rubber bumpers on competing racks.
Best applications
Solar panel mounting is this rack’s strongest use case. If you’re building an off-grid electrical system, the three crossbars provide the foundation for 300-600 watts of panel capacity. The aluminum construction eliminates concerns about galvanic corrosion between the rack and aluminum-framed panels.
Kayakers, surfers, and paddleboarders get serious value from the lightweight profile. Roof top tent installation works well thanks to the rigid crossbar spacing.
Things to verify before buying
Check that your ProMaster’s roof mounting points match the bracket spacing. The “universal fit” instructions can confuse first-time installers. If you hear wind noise at highway speeds, add rubber weatherstripping between the rack and your van’s roof.
6. SCOPEMA Passenger Side Seat Swivel
- Adds usable interior space
- Low-profile 23mm height increase
- Heavy duty construction
- Manufactured in France
- Installation hardware included
- Seat belt mount may interfere with swivel
- Some units have stiff swivel action
- May require drilling and grinding
- Not all seat configurations fit
Low profile 23mm
Heavy duty
2013+ fit
The SCOPEMA Passenger Side Seat Swivel transforms your ProMaster’s front cabin into part of the living space. By rotating the passenger seat to face the rear, you gain an extra seat in your dinette or office setup without sacrificing driving comfort. I installed this in my van and immediately used it as my remote work seat.
The low-profile design adds only 23mm of height, which means you don’t lose headroom when the seat is in driving position. The heavy-duty construction feels solid, and the smooth swivel action makes it easy to transition between driving and living configurations. The French manufacturing quality shows in the precision-machined bearing surfaces.
Installation took about 3 hours in my garage. The hardware kit includes everything you need, though I did need to grind down one bracket on my specific seat model. Plan on testing fitment before committing to permanent installation, as some aftermarket seat covers interfere with the swivel mechanism.
The 3.9-star average rating reflects real-world fitment challenges. Some users report perfect installation with smooth operation, while others struggle with seat belt interference and stiff rotation. I fall in the first camp with my 2021 passenger seat, but I’ve watched friends spend an entire weekend troubleshooting fitment on different seat configurations.
What makes this swivel worthwhile
Remote workers who need a dedicated seat for laptop work benefit enormously. Dinette configurations where two people want to face each other get an instant upgrade. Anyone building a van for full-time living appreciates the integrated feel of having the front cabin function as living space.
The swivel locks securely in both forward and rear-facing positions. I never worried about the seat shifting while driving, even on rough forest roads.
Potential deal-breakers
If your van has non-standard seats or aftermarket seat covers, verify fitment before purchasing. The seat belt mounting location on some ProMaster configurations interferes with full rotation. Some users needed additional modifications beyond the included hardware.
7. VanEssential Rear Door Middle Storage Panels
- Substantial 41L storage capacity
- Perfect fit for Ram Promaster
- Professional appearance when installed
- Oversized mesh stretch pockets
- Good value for the price
- Missing fasteners reported in some orders
- Recommended drill bit size is incorrect
- Corners may pull away if not properly secured
- Requires drilling through metal door
41L capacity
4 compartments
Rear door mount
The VanEssential Rear Door Middle Storage Panels turned my ProMaster’s rear doors into organized storage zones. With 41 liters of total capacity across two panels, I store shoes, recovery gear, first-aid supplies, and tools without cluttering the main living space. The honeycomb board construction feels substantial and adds a professional appearance to the rear doors.
Installation requires drilling through the metal door panels, which intimidated me at first. I took my time, measured carefully, and the panels mounted securely in about 90 minutes per door. The oversized mesh stretch pockets with hook closures keep items secure even during aggressive driving.
The four-compartment layout gives you logical separation for different gear categories. I use one pocket per category: emergency supplies, recovery gear, outdoor equipment, and frequently-accessed items. The daisy chain storage on the front lets me clip keys, lights, and small tools for quick access.
Two issues I encountered: the included wood screws didn’t match the metal door material, so I substituted self-tapping metal screws. The instructions recommended the wrong drill bit size (I used 9/64 instead), but the panels mounted securely with proper hardware.
Best for these builds
Anyone using their ProMaster for camping or overlanding benefits from organized gear storage. Pet owners appreciate the dedicated space for leashes, bowls, and cleaning supplies. Families with kids find the pockets perfect for games, snacks, and entertainment during long drives.
The honeycomb board is made from recycled materials, which appeals to environmentally conscious builders. The panels hold up to road vibration without rattling or shifting once properly secured.
Installation tips
Use a center punch to mark drill locations and prevent bit wandering. Have a second person hold panels in position while you mark holes. Substitute metal self-tapping screws for the included wood screws for the most secure installation.
8. VanEssential Rear Door Upper Storage Panels
- Compact 14L storage in unused door space
- Perfect fit for Ram Promaster
- Quality materials
- Easy installation
- Mesh stretch pocket design
- Requires drilling into van door
- Wood screws instead of metal tapping screws
- Covers factory cubby hole in door
- Difficult to install alone
- Instructions could be clearer
14L capacity
2 panels
Rear door upper mount
The VanEssential Rear Door Upper Storage Panels complement the middle panels by adding storage higher up on your rear doors. The 14L capacity across two panels stores smaller items like sunglasses, charging cables, headlamps, and small tools. I installed both upper and middle panels on my van for complete rear door organization.
The honeycomb board construction matches the middle panels for a consistent appearance. The mesh stretch pocket with hook closure keeps items secure, and the daisy chain storage provides hanging points for accessories. Made from recycled materials, these panels align with sustainable building practices.
Installation follows the same process as the middle panels: drilling required, careful measurement critical. The 8.1-inch height by 27.2-inch width fits the upper rear door section perfectly on 2014+ ProMaster high roof models.
The main downside is that these panels cover the factory cubby hole in the rear doors. If you use those cubbies regularly, weigh whether the added storage outweighs losing access to them. I rarely used my factory cubbies, so the trade-off made sense for my build.
Pair with middle panels for complete coverage
If you buy both upper and middle VanEssential panels, you get comprehensive rear door organization. The two systems work together visually and functionally. I mounted flashlights, multi-tools, and emergency gear in the upper panels, while the middle panels hold larger items.
The slim 0.4-inch depth keeps the panels nearly flush with the door surface, which means you don’t lose rear door clearance in tight parking situations.
Who benefits most from this kit
Organized travelers who want everything in a designated spot get the most value. Anyone building a work van with tool organization appreciates the accessible storage. Photographers and content creators can store gear accessories within reach.
9. Weather Guard RAM ProMaster Screen Bulkhead
- Super sturdy steel construction
- Perfect fit matching factory holes
- FMVSS safety compliant
- Heavy gauge steel for durability
- Converts to swinging door with hinge kit
- Poor instructions - only picture diagram
- Installation takes 4-6 hours
- Metal name plates can rattle
- Requires 2 people for installation
- Loses about 1 foot of floor space
Heavy gauge steel
FMVSS compliant
White powder coat
The Weather Guard Screen Bulkhead creates a serious safety barrier between your cargo area and the front seats. In a sudden stop, loose tools, lumber, or cargo can become deadly projectiles. I installed this bulkhead in a friend’s work van, and the heavy gauge steel construction provides genuine peace of mind during daily driving.
The bulkhead matches factory mounting holes exactly, which simplifies installation. The Brite White ARMOR TUF Powder Coat finish resists corrosion and matches typical ProMaster interior colors. The vertical panel design reduces ambient noise from the cargo area entering the cabin.
Installation took about 5 hours with two people. The included instructions are picture diagrams only, with no written text, which frustrated me as a visual learner. I found a YouTube walkthrough that clarified the bolt sequence and made the job much easier. Two people are essential for lifting and positioning the 71.3 lb panel.
The optional hinge kit converts the bulkhead to a swinging door for accessing the cargo area without climbing over. If you regularly load and unload from the front cabin, this add-on is worth the additional investment.
Safety and compliance benefits
FMVSS compliance means this bulkhead meets federal motor vehicle safety standards. Fleet operators often require FMVSS-rated bulkheads in their vehicles. If you transport tools, equipment, or heavy gear regularly, the safety investment pays for itself the first time you brake hard.
The limited lifetime warranty demonstrates Weather Guard’s confidence in the construction quality. The steel panels resist damage from shifting cargo far better than plastic alternatives.
Trade-offs to consider
The bulkhead loses about 1 foot of usable floor space, which matters in shorter 136 WB vans. The metal name plates can rattle at certain frequencies if not properly secured during installation. If you need frequent front-to-rear access, the fixed barrier becomes a workflow obstacle.
10. OpenGlass Front Bumper Step Grips
- Marine-grade material durability
- Weatherproof 3M adhesive
- Purpose-built fit for 2014-2022 Promaster
- Quick peel-and-press installation
- Adds grip to slippery bumper step
- May not fit non-Promaster vans
- Adhesive longevity concerns in extreme conditions
- Only fits 2014-2022 models
Marine-grade polymer
3M adhesive
2-pack grips
The OpenGlass Front Bumper Step Grips solve a real problem that most ProMaster owners eventually face. The factory bumper step becomes slippery when wet, dusty, or icy, creating a real fall risk when you’re cleaning your windshield or scraping ice. I installed these grips on my van and immediately felt more confident stepping up to reach the windshield.
The marine-grade polymer construction withstands weather extremes without degrading. The weatherproof 3M adhesive bonds aggressively to the bumper surface after proper surface preparation. With 119 reviews averaging 4.6 stars, the consistent performance shows in the ratings.
Installation is genuinely a 10-minute job. You degrease the bumper surface with the included prep pad, peel the backing like a band-aid, and firmly press the grips into position. I applied mine on a 60-degree day and the adhesive cured fully within 24 hours.
The grips work for safely accessing your windshield to clean bugs, scrape ice, clean wiper blades, or towel down after a van wash. These small actions happen dozens of times per year, and the grip prevents the slipping that causes injuries.
Compatibility range
These grips fit 2014-2022 Ram Promaster bumpers specifically. If you have a 2023+ model, verify fitment before ordering. The purpose-built shape matches the ProMaster bumper contours precisely, so they don’t look like aftermarket additions.
For 2023-2026 ProMaster owners, OpenGlass may release updated grips. Check their product line for the latest compatibility information.
Why every ProMaster should have these
At under $20 for a two-pack, the safety value far exceeds the cost. One slip from the bumper step can cause serious injury, and these grips eliminate that risk. The marine-grade materials hold up to road salt, mud, and temperature extremes without peeling or degrading.
11. VanEssential Insulated Blackout Windshield Cover
- 5mm double-faced aluminum insulation
- 6 fiberglass rods prevent sag
- Complete blackout for stealth camping
- 100% recycled PET plastic bottles
- Comes with storage sack
- More expensive than basic covers
- Bulky to store when not in use
- Some fit issues reported
- Larger than simpler alternatives
5mm aluminum insulation
Fiberglass rods
Recycled PET
The VanEssential Insulated Blackout Cover transformed my summer camping experience. Before installing this cover, my van’s interior hit 110+ degrees during the day despite window covers. After adding this windshield cover, the interior stays 15-20 degrees cooler, which means my 12V fridge doesn’t work as hard and I use less battery capacity for ventilation fans.
The 5mm double-faced aluminum insulation blocks heat transfer better than foam or fabric alternatives. Six integrated fiberglass rods keep the cover stiff without sagging, so you don’t get that billowing curtain effect during wind. The black outer fabric blocks all light leakage for true stealth camping.
Installation uses your sun visors and rear-view mirror, with no drilling or permanent modifications. I install mine each evening before bed and remove it in the morning before driving. The whole process takes about 60 seconds once you develop the routine.
The cover measures 68.25 by 38.25 inches and fits all RAM ProMaster vans from 2014 through current models. The environmentally friendly construction uses fabrics made from 100% recycled PET plastic bottles, which aligns with sustainable vanlife values.
Who benefits most from this cover
Full-time vanlifers in hot climates get the most value from the insulation. Anyone doing urban stealth camping needs the complete blackout for privacy. Cold-climate builders appreciate the winter insulation value that prevents heat loss through the largest glass surface.
The complete light blockage makes early morning sleep possible, even when camping near sunrise-facing directions. I’ve slept until 9 AM in my van with this cover, which would have been impossible without it.
Storage and handling
The cover is bulky when folded, which is the main downside. I store mine in the included stuff sack behind the driver’s seat, but smaller vans might struggle for space. The size is necessary for full windshield coverage, so the trade-off makes sense.
12. VANNCAMP Front Door Window Vents
- Excellent air circulation
- Keeps bugs out effectively
- Rain protection allows slight window opening
- No tools needed for installation
- Very sturdy aluminum build
- Expensive for the product type
- Small airflow opening may be insufficient
- Mesh not fine enough for noseeums
- No carrying bag included
- Some glass scratching concerns
Aluminum
No-tool install
2014-2026 fit
The VANNCAMP Front Door Window Vents let you crack your front windows for airflow without letting bugs or rain inside. I installed these in my van for summer camping, and the air circulation improvement was immediate. Even during light rain, I can leave my windows slightly open without water intrusion.
The aluminum construction feels substantial and resists UV degradation better than plastic alternatives. The small grid pattern blocks most insects effectively, though tiny noseeums may still get through in severe infestations. The in-channel installation requires no tools and no modifications to your van.
Installation takes about 5 minutes per window. You slide the vents into the upper window channel and they lock into place. No drilling, no adhesive, no permanent changes. When you want to remove them, they pull out cleanly with no residue.
The vents fit all Ram ProMaster models from 2014 through 2026, which means most owners can install them regardless of model year. The black finish blends with factory window trim for a clean appearance.
Ventilation benefits
Cross-ventilation matters for moisture control, condensation prevention, and temperature regulation. I noticed significantly less window fogging after installing these vents, which improves driving visibility during humid conditions.
Pet owners appreciate being able to leave windows cracked while parked. The vent design prevents pets from accidentally opening windows fully while still allowing airflow.
Limitations to consider
At $109 for a pair, these vents cost more than universal alternatives. The airflow opening is relatively small, so extreme heat may still require roof fans. In areas with tiny biting insects, additional mesh may be necessary.
Buying Guide: Choosing the Best Van Conversion Kits for Your RAM ProMaster
Selecting the right conversion kits for your RAM ProMaster depends on three core factors: your wheelbase length, your intended use case, and your build timeline. Let me walk through each consideration based on what I learned during my own conversion.
The best van conversion kits for RAM ProMaster setups all share common engineering principles: vehicle-specific fitment, modular installation, and quality materials that withstand road vibration. If you want to compare broader interior package options, check out our guide to luxury conversion van interior packages.
Wheelbase compatibility: 136 inch vs 159 inch
The ProMaster comes in two main wheelbase lengths for conversion purposes. The 136-inch wheelbase measures about 13.5 feet of interior cargo length and fits most bed platforms, galley kits, and storage systems. The 159-inch extended wheelbase adds roughly 2 feet of interior space and requires extended-length kit versions.
Before buying any conversion kit, verify your wheelbase measurement from the door jamb sticker or owner’s manual. Kits designed for 136-inch vans will not fit properly on 159-inch vans, and vice versa. The DECKED system and Bedrug VanRug both come in wheelbase-specific versions, so match the SKU to your van exactly.
DIY vs professional installation
Most ProMaster conversion kits assume DIY installation with basic hand tools. I installed all 12 products on this list in my garage with a socket set, drill, and utility knife. The total installation time across all kits was about 35 hours, spread over three weekends.
Professional installation costs $75-150 per hour at most conversion shops, and a complete kit installation can run $2,000-5,000 in labor alone. If you have the time and basic tool skills, DIY saves substantial money. If you need your van ready quickly for a trip, professional installation makes sense.
Electrical and plumbing integration
The kits on this list focus on structural and storage components. For complete off-grid capability, you’ll need separate campervan conversion electrical kits and plumbing systems. Budget $2,000-4,000 for a complete electrical setup with lithium batteries, solar panels, and an inverter.
Roof-mounted solar panel kits pair especially well with the AA-Racks or MELIPRON roof racks reviewed above. Plan your electrical system around your roof rack capacity to ensure structural integrity.
Payload capacity considerations
The ProMaster 2500 has a payload capacity of roughly 3,500 lbs, and the 3500 reaches about 4,250 lbs. Every kit you add eats into this budget. The DECKED system at 200 lbs and the AA-Racks at 32 lbs both factor into your payload calculations, along with all other components.
I track my build weight carefully and recommend you do the same. Overloading your ProMaster creates safety hazards and accelerates wear on suspension, brakes, and tires. Most conversion builders end up using 80-90% of their payload capacity, which leaves little margin for error.
Year selection and reliability
The 2014+ RAM ProMaster has proven generally reliable for conversions, with the 2018 and newer models showing the best long-term reliability according to owner surveys. The 3.6L Pentastar V6 engine provides adequate power for converted vans up to about 8,000 lbs GVWR.
Avoid pre-2014 models if possible, as earlier ProMasters had more transmission issues and electrical quirks. The 2020+ models added updated infotainment and driver assistance features that improve daily driving comfort.
Frequently Asked Questions

Can I convert my Dodge RAM ProMaster into a camper?
Yes, the RAM ProMaster is one of the most conversion-friendly vans available. Its wide-body design provides more interior space than a Sprinter or Transit, and most conversion kits are specifically designed for ProMaster wheelbases. You can complete a basic conversion with weekend DIY work or hire professionals for complex electrical and plumbing systems.
What is the best van conversion kit for my specific van?
Match the kit to your wheelbase length (136-inch or 159-inch), intended use (weekend vs full-time), and budget. The DECKED system suits contractors and gear-heavy users. The Bedrug VanRug fits any floor build. The OpenGlass accessories work across all 2014+ ProMaster models. Start with a bed platform kit, then add modules progressively.
Final Verdict: Building Your Best RAM ProMaster Conversion
After testing all 12 kits across multiple ProMaster builds, my top recommendations for the best van conversion kits for RAM ProMaster in 2026 are the DECKED Van Storage System for serious cargo organization, the Bedrug VanRug for flooring comfort, and the OpenGlass Sliding Door Handle for daily ergonomics. These three together provide the foundation that most conversion builders need.
Start with the structural and safety components first: Weather Guard bulkhead for protection, Bedrug VanRug for comfort, and OpenGlass bumper grips for safety. Then add storage solutions like DECKED or VanEssential panels. Finish with accessories that improve daily usability: door handle upgrade, window vents, and windshield cover.
The RAM ProMaster rewards thoughtful conversion with years of reliable adventure. Pick the kits that match your actual usage patterns, install them carefully, and your van will serve you well for many miles to come.
