Maximizing Exterior Storage on Your Full-Time RV

Living full-time in an RV means treating every square inch of space as premium real estate. The interior must remain a sanctuary for sleeping, cooking, and working, which means heavy, dirty, or occasionally used gear needs to find a home outside. Relying solely on factory pass-through bays often leads to a disorganized mess where finding a single tool requires unloading half the rig.

Maximizing exterior storage is not just about adding more containers; it is about strategic weight distribution and utilizing dead space. The bumper, the ladder, the hitch, and even the under-chassis area represent prime, untapped storage zones that can hold everything from sewer hoses to generators. By shifting these bulky items outward, the interior cabin becomes more livable and less claustrophobic.

However, external storage requires a disciplined approach to weight limits and security. Adding weight to the perimeter of an RV alters its towing dynamics and can overload specific structural points. The goal is to choose rugged, purpose-built gear that protects your investments from highway-speed winds, torrential downpours, and opportunistic theft.

Bumper Storage Box – MORryde Cargo Box SP56-115

The RV bumper is often ignored, but it is the perfect spot to mount heavy, bulky equipment like generators, power cords, or leveling blocks. The MORryde Cargo Box SP56-115 solves this by providing a dedicated, lockable metal vault that mounts securely to a standard 4-inch square bumper. It keeps high-value, dirty utility items completely out of the main living spaces and pass-through compartments.

Built with heavy-duty powder-coated steel, this box is engineered to withstand road debris and harsh weather. It features a weather-resistant seal to keep moisture out, and its dual-locking latch mechanism provides robust security against theft. The top-loading design makes it incredibly easy to access gear without having to bend down or squeeze into awkward angles.

• Materials: Powder-coated steel
• Mounting Type: 4-inch square bumper mount
• Security: Dual-locking latches
• Best For: Generators, heavy tools, and electrical cords

Before buying, confirm that the RV’s bumper is structurally rated to handle the combined weight of this heavy steel box and its contents. Many travel trailer bumpers require reinforcement brackets before adding load-bearing accessories. This box is ideal for travelers carrying expensive generators or heavy tools, but it is not suitable for ultra-lightweight trailers with flimsy spot-welded bumpers.

Hitch Cargo Carrier – Curt 18153 Basket Carrier

When the interior is packed to the brim, a hitch-mounted cargo carrier acts as an instant basement extension. The Curt 18153 Basket Carrier utilizes the rear 2-inch receiver hitch to carry bulky items like firewood, coolers, or portable waste tanks. It keeps wet, smelly, or dirty items completely isolated from the clean interior of the rig.

This heavy-duty steel carrier features a 500-lb carrying capacity and high, 6-inch side walls to keep cargo secure over bumpy terrain. The folding shank design is a game-changer for full-timers, allowing the basket to fold up flat against the back of the RV when empty to save space in tight campsites. Its mesh floor makes it incredibly easy to clean with a quick hose-down after a muddy trip.

• Capacity: 500 lbs
• Receiver Size: 2-inch
• Key Feature: Folding shank for space savings
• Best For: Coolers, firewood, and portable waste tanks

This carrier requires a 2-inch receiver hitch, and the added length will increase the tail-swing of the RV during tight turns. Users must ensure that license plates and tail lights remain visible when the basket is fully loaded. It is a perfect fit for active campers who need quick access to outdoor gear, but it might not be ideal for those with rear-mounted spare tires that block the folding mechanism.

RV Ladder Rack – Stromberg Carlson LA-102 Bike Rack

The rear ladder is often underutilized vertical real estate that is perfect for carrying awkward, lightweight items like bicycles. The Stromberg Carlson LA-102 Bike Rack clamps directly onto the existing ladder, keeping bikes secure and off the ground without taking up precious hitch space. It transforms an idle structural feature into a highly functional storage solution.

Constructed from lightweight aluminum, this rack does not add unnecessary weight to the rear wall of the RV. It features secure cradles and tie-down straps that prevent bicycles from swaying and scraping against the rig’s exterior gel coat. The hook-and-loop straps make loading and unloading a two-minute process, which is ideal for quick stops on long travel days.

• Capacity: 2 bicycles (up to 50 lbs total)
• Material: Lightweight aluminum
• Attachment Point: Existing RV exterior ladder
• Best For: Road bikes and lightweight mountain bikes

Standard RV ladders have strict weight limits, typically capping out around 250 pounds, so this rack is strictly meant for standard bicycles, not heavy e-bikes. Drivers must account for the extra depth added to the rear of the vehicle when backing into tight campsites. It is an excellent choice for solo travelers or couples with lightweight bikes, but a poor fit for families with multiple heavy cruiser bikes.

Under-Chassis Storage – Lippert 236558 Bin

The underside of an RV is a vast expanse of unused space that is perfect for storing items that are rarely used but absolutely necessary. The Lippert 236558 Under-Chassis Storage Bin mounts directly to the RV frame rails, hanging below the floorboards. It is the ultimate hiding spot for spare parts, winterizing fluids, or extra leveling blocks that otherwise clutter primary compartments.

This system features a durable, impact-resistant plastic bin housed inside a heavy-duty steel bracket system that slides out smoothly from either side of the rig. It utilizes a lockable latch to keep gear secure from road vibrations and potential theft. Because it mounts centrally, it helps keep the RV’s center of gravity low, which improves towing stability.

• Weight Capacity: Up to 100 lbs
• Access: Dual-side slide-out mechanism
• Material: Impact-resistant polymer with steel framing
• Best For: Spare parts, extra leveling blocks, and seasonal gear

Installation requires drilling into the RV’s chassis frame, which may require careful measurement to clear plumbing lines and slide-out mechanisms. Ground clearance is the primary concern here; this bin is best suited for fifth wheels and larger travel trailers with high ground clearance rather than low-slung campers. It is perfect for full-timers who need a set-and-forget spot for emergency recovery gear.

Sewer Hose Carrier – Valterra EZ Hose Carrier

Valterra A04-5094BK RV Adjustable EZ Hose Carrier with Lockable Door Cap, Black

Keeping sanitation gear completely isolated from drinking water hoses and camp kitchen setups is a fundamental rule of RV hygiene. The Valterra EZ Hose Carrier provides a dedicated, sealed tube designed solely for storing wet, dirty sewer hoses and fittings outside the main storage bays. It eliminates the risk of cross-contamination and keeps unpleasant odors completely outside.

This carrier features an adjustable length design that expands from 50 to 80 inches, accommodating long hoses with pre-attached fittings. Made from heavy-duty black plastic, it resists UV damage and road grime without rusting or cracking over time. The tethered cap features a pad-lockable latch to ensure the hose remains secure during bumpy transit.

• Length: Adjustable from 50 to 80 inches
• Material: UV-stabilized heavy-duty plastic
• Mounting Options: Under-chassis, bumper, or frame mount
• Best For: Standard RV sewer hoses and elbow fittings

Mounting requires self-tapping screws or heavy-duty zip ties to secure the brackets to the RV frame or bumper. Ensure the carrier is mounted in a spot that allows easy access near the wet bay but does not block low-point drains or stabilizer jacks. This is an essential safety and sanitary upgrade for every full-time RVer, regardless of rig size.

A-Frame Cargo Tray – Stromberg Carlson CC-255

The tongue of a travel trailer (A-frame) is highly underutilized space that sits right above the LP tanks and battery box. The Stromberg Carlson CC-255 Cargo Tray mounts directly over this area, creating a heavy-duty elevated platform. This is the absolute best spot to store heavy, vibrates-frequently gear like generators, which are notoriously difficult to haul inside the cabin.

This tray is constructed from high-strength steel and can support up to 300 pounds of cargo without interfering with the towing vehicle’s turning radius. It features an adjustable height and width design, allowing it to clear almost any configuration of dual LP tanks or battery boxes. The open mesh floor provides plenty of tie-down points for ratchet straps to keep expensive gear locked down.

• Weight Capacity: 300 lbs
• Material: Heavy-duty steel mesh
• Compatibility: Most A-frame travel trailers
• Best For: Generators, heavy toolboxes, and fuel cans

Adding weight directly to the tongue increases the overall hitch weight of the trailer, which affects the tow vehicle’s payload capacity. Buyers must ensure their tow vehicle can handle the increased tongue weight before loading heavy generators onto this tray. It is an indispensable tool for travel trailer owners who dry camp or boondock frequently and need reliable generator access.

Spare Tire Trash Bag – Trasharoo Spare Tire Bag

Wet trash, recycling, and smelly campfire wood have no business sitting inside an RV cabin or taking up valuable basement space. The Trasharoo Spare Tire Bag buckles directly over the exterior spare tire, providing a rugged, high-capacity external trash can. It keeps pests, leaks, and odors completely away from the living quarters.

Made from heavy-duty 900-denier canvas, this bag is water-resistant and features nylon buckles and straps that can handle up to 50 pounds of weight. It includes a drain grommet at the bottom for easy hose-out cleaning when leaks occur. The exterior features additional mesh pockets and MOLLE webbing for storing trash bags, gloves, or small tools.

• Capacity: Up to 50 lbs / 30 gallons of trash
• Material: 900D weather-resistant canvas
• Mounting System: X-strap buckle system for spare tires
• Best For: Trash, recycling, firewood, and muddy recovery gear

The bag must be secured tightly to prevent shifting on the highway, and the canvas will eventually fade if exposed to intense UV rays year-round. It requires a rear-mounted spare tire, ladder, or tailgate to mount properly, making it unusable for rigs without these mounting points. It is a must-have for boondockers who practice leave no trace and need a reliable way to haul garbage back to civilization.

Heavy-Duty Storage Tote – Rubbermaid ActionPacker

Even with specialized racks and carriers, a rugged, all-weather storage tote is essential for organizing loose gear in pass-through bays or open cargo baskets. The Rubbermaid ActionPacker is built specifically to survive extreme conditions that would shatter standard household storage bins. It serves as a stackable, lockable vault for tools, cords, and recovery gear.

This tote features a virtually indestructible impact-resistant construction that resists cracking even in freezing temperatures. The lockable latches snap shut with authority, securing the lid against wind, rain, and curious wildlife. The textured lid allows for secure stacking, maximizing the vertical space inside deep RV basement compartments.

• Material: Impact-resistant polyethylene
• Latching: Lockable steel latches
• Durability: Weatherproof and shatter-resistant
• Best For: Tow straps, tire changers, brass plumbing fittings, and electrical adapters

These totes are heavier and bulkier than cheap department store bins, which means they consume slightly more raw cargo weight. However, their durability means they do not need to be replaced every season due to UV degradation or heavy impact. This is the gold standard for full-timers who store heavy recovery gear, hoses, or brass fittings that require heavy-duty protection.

Folding Trunk Organizer – Fortem Car Organizer

Large exterior storage bays are great for capacity but terrible for organization, often turning into black holes where small items disappear. The Fortem Car Organizer keeps daily-use items—like slide-out lubricants, dog leashes, work gloves, and flashlights—neatly partitioned and easily accessible. It bridges the gap between massive storage compartments and the small, loose gear that keeps an RV running.

This organizer features reinforced base plates and rigid side walls that prevent it from collapsing when loaded with heavy tools. It includes adjustable compartments, mesh side pockets, and a sturdy lid to keep dust and dirt off the stored items. The bottom features non-slip strips that prevent the organizer from sliding around the slick plastic floors of RV storage bays during travel.

• Material: Heavy-duty polyester with reinforced base
• Features: Collapsible design, mesh pockets, non-slip bottom
• Security: Foldable cover lid included
• Best For: Aerosol sprays, small tools, flashlights, and dog gear

While highly durable for fabric organizers, this is not designed to sit out in direct rain or be exposed to harsh road elements. It should be kept inside a pass-through compartment, under-chassis bin, or the back of a tow vehicle. It is perfect for RVers who are tired of rummaging through giant plastic bins just to find a simple screwdriver or roll of plumbers tape.

How to Calculate Your RV Cargo Carrying Capacity

Before loading up every bumper rack, tongue tray, and under-chassis bin with gear, understanding Cargo Carrying Capacity (CCC) is critical. Overloading an RV is a fast track to blown tires, broken suspension leaf springs, and dangerous sway on the highway. Every RV has a yellow federal certification label, usually found on the forward left exterior wall or inside a cabinet door, listing the Gross Vehicle Weight Rating (GVWR) and the Unloaded Vehicle Weight (UVW).

To find the actual CCC, subtract the UVW and the weight of a full fresh water tank from the GVWR. Do not forget that water weighs approximately 8.3 pounds per gallon; running with a full 50-gallon fresh water tank instantly eats up over 400 pounds of your available cargo capacity. Additionally, any aftermarket modifications, propane tanks, and the hitch itself must be subtracted from this total before loading personal gear.

When distributing this calculated cargo weight, aim for balance both front-to-back and side-to-side. For travel trailers, maintaining a tongue weight of 10% to 15% of the total loaded trailer weight is crucial for preventing dangerous trailer sway. Regularly visiting a CAT scale at a truck stop is the only way to get accurate wheel-by-wheel weights to ensure individual axles and tires are not overloaded.

Tips for Weatherproofing Your Outdoor Gear

Outdoor RV storage means exposing your gear to a brutal cocktail of high-speed highway winds, blistering UV rays, road salt, and heavy downpours. Unprotected metal tools will rust overnight, and plastics will quickly become brittle and crack under direct sunlight. True weatherproofing starts with choosing materials like marine-grade stainless steel hardware, heavy-duty canvas, and UV-stabilized plastics for all external storage components.

To protect items inside non-waterproof carriers, utilize heavy-duty dry bags or silica-gel desiccant packs inside sealed plastic totes to manage condensation. Applying a layer of graphite lubricant to locks and padlocks prevents them from seizing up due to road grime and salt exposure. For canvas bags like spare tire trash carriers, a seasonal treatment with a UV-blocking fabric protector will extend their lifespan significantly by preventing dry rot.

Finally, inspect all exterior seals, latches, and mounting straps before every single travel day. Highway vibrations act like a jackhammer on loose fittings, turning tiny water leaks into flooded storage boxes. A quick wipe-down of rubber gaskets with silicone spray keeps them pliable, ensuring a watertight seal that keeps your valuable gear dry and ready for use at the next campsite.

Conclusion

Successfully managing outdoor storage transforms full-time RV life from a game of Tetris into a comfortable, organized lifestyle. By utilizing underused areas like bumpers, ladders, and frames with rugged, purpose-built gear, the interior of the rig remains a clean, relaxing home. Invest in high-quality storage solutions, monitor cargo weight carefully, and enjoy the freedom of a clutter-free journey.
