10 Best Cargo Storage Solutions For Exterior Van Doors For Full-Time RVers

Living full-time in a camper van means waging a constant war against clutter, where every square inch of interior space is sacred. When the cabinets are stuffed and the garage area is at capacity, the only logical place left to expand is outward onto your rear doors. Utilizing these exterior mounting points turns unused vertical space into a highly functional gear station for heavy, dirty, or frequently accessed equipment.

How to Maximize Your Van’s Exterior Storage Space

Before bolted-on accessories start piling up, it is crucial to analyze the structural limits of the vehicle’s rear doors. Most factory door hinges are not designed to support hundreds of pounds of bouncing cargo over washboard dirt roads. Upgrading to heavy-duty, 180-degree or 270-degree hinges is often the mandatory first step to prevent sagging, misalignment, and long-term sheet metal damage.

Smart exterior storage relies on organizing gear by frequency of use and environmental tolerance. Items that are dirty, wet, or bulky—such as recovery boards, fuel cans, and trash bags—belong outside to preserve interior air quality and living space. Grouping these items onto consolidated mounting systems keeps the van streamlined and prevents the exterior from looking like a disorganized hardware store.

Accessibility must also remain a priority, especially when trying to open the doors from the inside during camp setup or emergencies. Ensure that your chosen layout allows at least one door to open fully without requiring you to unload heavy gear first. Balance is key; overloading one door while leaving the other empty creates uneven wear on the door latches and hinges over thousands of miles.

Gear Storage Box – Aluminess Deluxe Cargo Box

A dedicated exterior cargo box acts as your van’s secondary garage, housing dirty, bulky, or smelly gear that has no business being inside your living space. Items like portable generators, recovery straps, tire inflators, and leveling blocks need to be secure from both the elements and theft. Utilizing a lockable box keeps these essentials accessible within seconds without tracking mud through your bedroom.

The Aluminess Deluxe Cargo Box stands out because it is constructed from lightweight, marine-grade aluminum, meaning it won’t rust or needlessly contribute to rear-axle weight capacity. It features a robust, weather-stripped seal that keeps dust and heavy rain out, alongside a reliable flush-mount locking latch.

Before purchasing, confirm your mounting setup, as this box cannot attach directly to the sheet metal of the door. It requires a compatible rear door rack or swing-away bumper system, which adds to the overall initial investment. It also blocks the rear window view completely on whichever side it is mounted.

• Dimensions: 30″ x 24″ x 16″
• Material: Powder-coated marine-grade aluminum
• Compatible with: Aluminess rear door mounts, Owl Vans Sherpa, and most universal steel carrier platforms

This setup is ideal for full-timers carrying high-value gear or recovery equipment who refuse to compromise on security. It is not the right choice for budget-conscious builders or those who prefer to keep their rear windows completely unobstructed.

Door Carrier Platform – Owl Vans B2 Carrier

Without a structural foundation, mounting heavy gear to a rear door is a recipe for warped sheet metal. A door carrier platform solves this by transferring the weight of your cargo directly to the vehicle’s heavy-duty door hinges rather than the fragile center of the door panel. It provides a rigid, secure grid to mount boxes, bikes, or fuel cans safely.

The Owl Vans B2 Carrier is engineered specifically for this load-bearing task, utilizing tig-welded aluminum to keep its own footprint incredibly light. What makes this carrier unique is its dual-purpose design: it functions simultaneously as a dual bike rack and a vertical accessory mounting platform. By mounting directly to the hinges, it prevents door deformation even when subjected to intense off-road vibrations.

Keep in mind that installation requires upgrading to 180-degree factory hinges on certain Sprinter models, and alignment is critical to ensure the doors still close smoothly. This is a highly vehicle-specific product, so owners of older or less common vans will need to look elsewhere for universal solutions.

• Material: Tig-welded aluminum
• Weight capacity: Up to 150 lbs
• Compatible vehicles: Mercedes Sprinter (2019+ and VS30 platforms)

This is the ultimate choice for Sprinter owners who want a premium, modular system that can adapt from carrying mountain bikes to hauling cargo boxes as travel seasons change. It is not suitable for those looking for a cheap, temporary mounting solution or non-Sprinter platforms.

Exterior Molle Panel – Flatline Van Co Molle Panel

When you have a collection of smaller gear items like axes, shovels, first aid kits, or small storage pouches, a massive cargo box is overkill. An exterior Molle (Modular Lightweight Load-carrying Equipment) panel provides a highly customizable grid that allows you to bolt on or strap down accessories exactly where you want them. This keeps frequently used tools visible and ready for immediate deployment.

The Flatline Van Co Molle Panel is a standout choice due to its precision laser-cut aluminum design and durable black powder coat. It features industry-standard spacing that accepts a wide range of mounting hardware, straps, and brackets, giving you total creative control over your layout. Its slim profile keeps your van’s overall length down while still offering substantial utility.

While highly versatile, this panel is designed to bolt onto specific ladder systems or door racks, meaning it is rarely a standalone solution. Users must be careful not to overload individual mounting slots with excessively heavy items, as this can cause localized flexing over time.

• Material: 3/16″ laser-cut aluminum
• Finish: Textured black powder coat
• Compatible with: Flatline Van Co ladders, custom DIY brackets, and standard Molle accessories

This panel is perfect for the active overlander who needs instant access to recovery tools and trail gear. It is not suitable for those who need to carry high-volume, bulky items that require fully enclosed weather protection.

Universal Gear Mount – Owl Vans Sherpa Carrier

If you need to mount a mix of heavy items—like metal jerry cans, traction boards, and small gear cases—without the bulk of a full-width platform, a universal plate carrier is the answer. It bridges the gap between a simple Molle panel and a full-size storage box by offering a heavy-duty, compact plate that bolts straight to your door hinges. This keeps your vehicle’s profile narrow while retaining maximum load capacity.

The Owl Vans Sherpa Carrier utilizes a unique, densely patterned hole layout that allows you to mount virtually any accessory at almost any angle. Crafted from solid billet aluminum parts and CNC-bent plates, it offers a level of structural rigidity that cheaper steel or thin aluminum plates simply cannot match. It moves with the door, ensuring that your heavy fuel cans or gear boxes don’t bounce independently of the vehicle.

Installation requires precise alignment of the door hinges, and you must ensure the door latches are in good working order to handle the concentrated load. It is a premium product with a price tag to match, making it a serious commitment for any rig build.

• Material: CNC-machined and bent aluminum
• Mounting pattern: Universal Sherpa pattern for RotopaX, DMOS shovels, and cargo boxes
• Compatible vehicles: Mercedes Sprinter, Ford Transit (specific models)

This carrier is the absolute benchmark for full-time off-grid travelers who need to mount heavy, dense gear like extra fuel and recovery tools securely. It is not recommended for casual travelers who only need to hang light soft goods or basic accessories.

Weatherproof Cargo Bag – Blue Ridge Overland Bag

Not all gear needs to be locked behind metal walls, but it still needs protection from road grime, rain, and UV rays. A weatherproof cargo bag is the perfect solution for hauling camp trash, wet wetsuits, dusty firewood, or muddy recovery gear. Keeping these smelly, damp items outside of your living space is vital for maintaining a comfortable interior environment.

The Blue Ridge Overland Spare Tire Trash Bag (often used as a universal cargo bag) is built from ultra-durable, UV-resistant vinyl and Cordura, designed to withstand years of highway speeds and harsh weather. It features a heavy-duty vinyl lining that can be easily hosed out after hauling wet trash or muddy gear, preventing mold and odors from taking root. Its integrated strap system allows it to mount securely to spare tires, ladders, or rear door platforms.

While highly durable, users should avoid packing sharp-edged tools directly against the fabric to prevent punctures. Regular cleaning of the heavy-duty buckles and straps is recommended, especially after traveling through dusty off-road environments or salt-heavy winter roads.

• Material: 500D Cordura and heavy-duty vinyl liner
• Mounting: Multi-strap system compatible with spare tires, ladders, and cargo grids
• Features: Integrated drainage grommets and exterior Molle webbing

This bag is the ideal choice for any RVer who wants a rugged, hose-out solution for trash and wet gear. It is not the right choice for those seeking high-security anti-theft storage for valuable electronics or tools.

Ladder Fuel Can Mount – RotopaX Deluxe Pack Mount

Carrying extra fuel or water is non-negotiable when venturing deep into remote off-grid territory. However, liquid containers are heavy and prone to dangerous leaks if they are subjected to shifting and vibration on the road. A dedicated, locking pack mount secures these fluids to your door-mounted ladder or utility panel, keeping them upright and structurally stable.

The RotopaX Deluxe Pack Mount is the gold standard for securing RotopaX containers, offering a unique, thread-locking design that prevents the container from spinning or vibrating loose. Made from anodized aluminum, this mount features a solid steel core thread that provides incredible holding power even when carrying heavy 4-gallon fuel packs. Its t-handle design allows for rapid, tool-free removal when it is time to refuel or use water.

Keep in mind that this mount is designed specifically for RotopaX-brand containers, meaning it will not work with standard jerry cans or other generic fluid jugs. You will also need a flat mounting plate, Molle panel, or dedicated ladder bracket to bolt this mount onto your rear door setup.

• Material: Anodized aluminum with steel threads
• Compatible containers: All RotopaX brand fuel, water, and emergency packs
• Mounting: Flat plate or specialized ladder brackets

This mount is a must-have for off-grid explorers who rely on RotopaX containers to extend their travel range. It is not suitable for those who prefer traditional metal jerry cans or lack a structured panel to mount it to.

Traction Board Mount – MaxTrax Mounting Pin Set

Traction boards are your best friend when stuck in deep sand, mud, or snow, but they are incredibly awkward to store inside a van due to their length and dirty nature. Securing them to the exterior rear doors ensures they are immediately accessible when a recovery situation arises. To prevent them from becoming projectiles or targets for theft, a highly secure, vibration-resistant mount is essential.

The MaxTrax Mounting Pin Set is designed specifically to lock down up to four MaxTrax recovery boards with absolute security. Constructed from high-strength stainless steel and quick-release nylon, these pins feature a simple quarter-turn lock that releases the boards in seconds without requiring tools. The top of each pin is designed to accept a padlock, giving you peace of mind when leaving your rig unattended in public spaces.

These pins are precision-engineered specifically for the hole spacing on authentic MaxTrax boards, meaning they may not align with budget-brand traction boards. You will need a flat mounting surface or specialized brackets to secure these pins to your rear door ladder or Molle panel.

• Material: Stainless steel and glass-filled nylon
• Capacity: Holds 2 or 4 MaxTrax MKII, XTREME, or JaxTrax boards
• Security: Padlock compatible for theft prevention

This setup is the premier choice for serious adventurers who run genuine MaxTrax boards and require fast, reliable deployment during off-road recoveries. It is not suitable for travelers using alternative traction board brands with different mounting configurations.

Rear Door Bike Rack – Thule Elite Van XT Rack

Hitch-mounted bike racks are popular, but they often block access to the rear doors, requiring you to swing or tilt a heavy assembly every time you need to grab something from the back of the van. A door-mounted bike rack solves this frustration by attaching directly to a single door, allowing you to swing the door open with the bikes still mounted. This keeps your rear entry fully functional while keeping your bikes secure and off the ground.

The Thule Elite Van XT Rack is a masterclass in clean, drill-free integration, clamping securely to the rear door of popular vans like the Ram ProMaster or Fiat Ducato. It utilizes lightweight but sturdy aluminum profiles to carry up to two bikes, and the wheel rails can be adjusted easily to find the perfect fit. When not in use, the rack folds up vertically, keeping the van’s footprint compact for tight parking spots.

It is important to note the weight limits on this rack, as it is designed for traditional road, gravel, or mountain bikes. If you ride heavy electric bikes, the weight may exceed the rack’s rating, requiring you to look at heavy-duty hitch options instead.

• Material: High-grade lightweight aluminum
• Weight capacity: 77 lbs total (approx. 42 lbs per bike max)
• Compatible vehicles: Ram ProMaster, Fiat Ducato, and select transit vans

This is the ideal solution for active road and trail cyclists who want effortless access to their rear doors without dealing with a bulky hitch rack. It is not suitable for owners of heavy e-bikes or vans without compatible door profiles.

Soft Storage Organizer – Overland Gear Guy Panel

Sometimes the best storage solutions are soft, lightweight organizers that utilize the interior-facing surface of your rear doors or hang within reach when the doors are swung wide open. These organizers are perfect for holding small, everyday essentials like flashlights, bug spray, dog leashes, cooking utensils, and first aid supplies. Keeping these items in dedicated pockets prevents them from rattling around in drawers or getting lost in deep cabinets.

The Overland Gear Guy Rear Door Organizer is custom-made in the USA using heavy-duty, marine-grade vinyl and rugged zippers that can handle years of abuse. It features a variety of pocket sizes, including slip pockets, zippered pouches, and mesh compartments, allowing you to categorize your gear with extreme precision. Its robust construction ensures it won’t sag or tear even when packed with heavier hand tools or camp kitchen gear.

Installation typically requires screwing the panel directly into the door’s plastic trim or sheet metal using self-tapping screws, which is a permanent modification. Because it is a soft organizer, it offers zero protection against theft, so it should only be used for low-value gear or when the doors are locked up for the night.

• Material: Marine-grade vinyl and heavy-duty mesh
• Mounting: Screw-in or snap-in installation (hardware included)
• Compatible vehicles: Custom-sized layouts available for Sprinter, Transit, and ProMaster

This organizer is perfect for organized campers who want to turn their open rear doors into a functional camp kitchen or tool station. It is not suitable for those who need secure, lockable exterior storage for high-value items.

Jerry Can Holder – Front Runner Single Mount

Standard 20-liter (5-gallon) NATO-style jerry cans are the undisputed classic choice for carrying extra fuel or water, but their heavy, boxy shape makes them difficult to secure. If they are not held in a rigid, vibration-proof cradle, they will rattle incessantly, damage your paint, or worse, rupture and leak. A heavy-duty, lockable holder is essential for carrying these heavy metal canisters safely over rough terrain.

The Front Runner Single Jerry Can Holder is built from black powder-coated, high-strength steel, designed to survive the harshest off-road environments. It features a robust, adjustable latch system that clamps down on the can to eliminate all rattles, alongside a lockable clasp to prevent fuel theft. Its low-profile frame can be bolted to rear door cargo platforms, ladders, or roof racks with ease.

Keep in mind that a full 5-gallon steel jerry can weighs around 45 pounds, which places significant stress on your rear door hinges. You must ensure your door mounting system is rated for this concentrated weight before bolting this holder in place.

• Material: Black powder-coated high-strength steel
• Compatible cans: Standard 20L / 5.3 gallon NATO/Scepter-style jerry cans
• Features: Lockable latch and rattle-free adjustable clamping mechanism

This holder is the perfect match for overlanders who prefer the durability of traditional steel jerry cans for extra fuel or water range. It is not suitable for those using plastic RotopaX systems or lightweight, non-standard fuel jugs.

Key Weight Distribution Tips for Rear Van Doors

Overloading the rear doors is one of the most common mistakes made by full-time RVers looking to maximize their storage footprint. While metal racks and carriers are incredibly strong, the vehicle’s door latches and sheet metal are the ultimate failure points when subjected to off-road forces. A good rule of thumb is to keep the combined weight of your rack and gear under 150 pounds per door, depending on the manufacturer’s specific guidelines.

Weight distribution should be balanced both vertically and horizontally across the rear axle. Try to mount your heaviest items—like full jerry cans or generators—as low and close to the hinges as possible to reduce leverage and stress on the door latches. Placing lighter items like recovery boards, traction pads, or soft trash bags higher up on the door or ladder keeps the center of gravity low and manageable.

Finally, regular maintenance is mandatory when carrying heavy loads on your doors. Check all mounting bolts, hinge pins, and door latch mechanisms every few thousand miles, especially after traveling down corrugated dirt roads. A small amount of preventive maintenance, like lubricating hinges and tightening loose mounting hardware, will prevent costly structural repairs down the road.

Conclusion

Optimizing your van’s rear doors with the right cargo solutions transforms your exterior into a highly organized, rugged gear center. By matching high-quality, vehicle-specific platforms with secure lockable storage, you can confidently hit the trail with all your essentials safely in tow. Invest in quality components, keep your weight distribution balanced, and enjoy a clutter-free interior living space.
