9 Essential RV Exterior Compartment Organization Gear Picks for Full-Time RVers

Stepping outside your rig only to spend twenty minutes digging through a chaotic pass-through bay for a single water fitting is a rite of passage every RVer quickly learns to hate. When living full-time on the road, your exterior compartments serve as your basement, garage, and utility closet all rolled into one highly constrained space. Mastering this storage puzzle requires moving away from loose piles and transitioning to a systematic, high-utility gear layout that withstands thousands of miles of road vibration.

Maximizing Utility in Your RV Basement Storage

RV basement storage is deceptively large but notoriously awkward to utilize efficiently. High ceilings in pass-through bays often result in wasted vertical space, while deep, dark corners become graveyard zones for tools you forget you even own. To maximize this footprint, think in three dimensions by utilizing stacking systems, wall-mounted racks, and pull-out mechanisms that bring the gear to you.

Proper zone division is the foundation of a highly functional bay layout. Dedicate specific zones for wet utilities (freshwater and sewer hoses), dry utilities (electrical cords and adapters), setup tools (blocks and chocks), and seasonal gear. Keeping these categories physically isolated prevents cross-contamination and ensures you can execute setup and teardown routines on autopilot, even in a pouring rainstorm.

Hose Reel – MorRyde Easy Reel Hose Spooler

Freshwater hoses are notoriously stiff, especially in cold weather, and tend to spring back into unruly coils the moment they are released. Leaving them loose in a bay leads to kinks, tangles, and wasted floor space that could be used for heavier gear. A dedicated spooler tames this chaotic hose, keeping it condensed and ready to deploy at a moment’s notice.

The MorRyde Easy Reel Hose Spooler stands out because of its rugged, all-steel construction and smooth hand-crank operation. Unlike cheap plastic reels that crack under UV exposure or freezing temperatures, this unit features a corrosion-resistant powder coat and can be mounted directly to the compartment floor or left freestanding for placement flexibility. It utilizes a simple pin-lock mechanism to keep the spool from unraveling while transit vibrations shake the rig.

Before purchasing, verify your bay’s vertical clearance, as this unit stands just over 13 inches tall. It is designed to hold up to 150 feet of standard 5/8-inch hose, though stiff, cold-weather hoses might reduce this capacity slightly.

• Dimensions: 14.5” x 12.5” x 13.25”
• Capacity: Up to 150 feet of 5/8-inch hose
• Mounting: Bolt-down floor mount or freestanding

This spooler is perfect for full-timers with large pass-through bays who value speed and durability over absolute weight savings. It is not ideal for small camper vans or rigs with shallow, carpeted side compartments where vertical clearance is under 14 inches.

Storage Trunk – Plano Black Sportsman Trunk

Loose items like heavy-duty extension cords, brass fittings, leveling blocks, and spare parts will migrate across your storage bays during travel. Without heavy-duty containment, these items can damage delicate compartment walls or crush soft gear. Heavy-duty trunks provide a rigid barrier, protecting your gear from both impact and environmental dust.

The Plano Black Sportsman Trunk is the benchmark for rugged, stackable storage due to its high-impact plastic formulation and reinforced lid design. Molded grooves allow multiple trunks to lock together securely, preventing dangerous shifts when cornering on winding mountain roads. The heavy-duty snap-down latches keep the lid tightly sealed, while integrated padlock tabs offer an extra layer of security if you choose to strap the trunk to an exterior cargo rack.

These trunks come in various sizes, but the 68-quart model strikes the ultimate balance between storage capacity and manageable carrying weight. Ensure you measure your compartment door openings rather than just the interior dimensions, as many RV doors have a lip that reduces the usable clearance for sliding large bins inside.

• Capacity: 68 Quarts (approx. 17 gallons)
• Material: High-impact, heavy-duty molded plastic
• Features: Stackable design, tie-down brackets, snap-fit latches

This trunk is a must-have for RVers who need to store heavy, dirty recovery gear or bulky electrical cords in a clean, dry environment. It is not the right fit for ultra-shallow bays or for owners who struggle to lift bins weighing over 40 pounds when fully loaded.

Utility Bag – Kohree RV Hose Storage Bags

Storing freshwater, gray water, and black water components in close proximity is a recipe for cross-contamination. Traditional plastic bins can trap moisture, leading to mold growth and unpleasant odors in your enclosed storage bays. Breathable, color-coded utility bags solve this by organizing hoses by function while allowing residual moisture to evaporate safely.

Kohree RV Hose Storage Bags provide a simple, highly visual system with color-coded labels: blue for fresh water, black for black water, and yellow for electrical cords. The top half of each bag is constructed from a heavy-duty breathable mesh, which ensures air flows freely to dry out damp hoses after disconnect. The bottom is made of durable, waterproof oxford cloth, preventing drips from leaking onto your compartment floors.

Each bag features a sturdy drawstring closure and a convenient carrying handle, making transport to and from the utility pedestal effortless. While the mesh is exceptionally durable, avoid dragging these bags across abrasive gravel campsites, as sharp rocks can snag the mesh fibers over time.

• Colors: Blue (Fresh Water), Black (Sewer), Yellow (Electrical)
• Dimensions: 16” diameter x 10” depth
• Material: 600D Oxford fabric with rubberized mesh tops

These bags are highly recommended for any RVer looking to streamline their setup routine and eliminate the guessing game of which hose is which. They are not suitable for storing heavy, sharp-edged steel tools or bulky jacks that require rigid containment.

Sliding Tray – MORryde Cargo Sliding Tray

Deep pass-through bays require you to crawl on your hands and knees to reach items stored in the center of your rig. This physical strain often leads to organizing your gear based on access convenience rather than weight distribution or frequency of use. A rolling cargo tray solves this accessibility bottleneck by sliding the entire contents of your bay out into the open air.

The MORryde Cargo Sliding Tray is built to survive the harsh realities of heavy-duty mobile storage. Constructed with a rugged steel frame and high-density wooden deck, it operates on heavy-duty ball-bearing slides that glide smoothly even when loaded to maximum capacity. A dual-direction travel design allows you to access your gear from either side of your travel trailer or fifth wheel, doubling your accessibility options.

Installation requires drilling directly into your RV compartment floor, so verifying the location of under-floor tanks and wiring harnesses is critical before mounting. Keep in mind that these trays weigh a significant amount themselves, which directly reduces your overall cargo carrying capacity (CCC).

• Weight Capacity: Up to 800 lbs (depending on model size)
• Extension: 60% or 100% sliding options
• Construction: Powder-coated steel with carpeted floor

This sliding tray is an essential luxury for full-time fifth-wheel owners who carry heavy generators, toolboxes, or bulk storage bins. It is not practical for lightweight travel trailers or camper vans where every pound of cargo capacity must be fiercely guarded.

Tool Holder – Grip Tight Magnetic Tool Bar

Screwdrivers, wrenches, pliers, and flashlights are constantly needed for quick adjustments around the rig, but keeping them in a deep toolbox makes rapid access impossible. Wall-mounting your most frequently used hand tools frees up valuable floor space in your compartments. It also keeps your essential repair gear visible and within arm’s reach for roadside emergencies.

The Grip Tight Magnetic Tool Bar utilizes heavy-duty permanent magnets encased in a sleek steel channel to hold metal tools securely in place. Unlike plastic clips that degrade over time or lose their grip in cold weather, these magnetic bars maintain their strength indefinitely. The pre-drilled mounting holes make it easy to secure the bar to a compartment wall, inner door skin, or the side of a storage cabinet.

While the magnets are exceptionally strong, road vibrations can eventually dislodge exceptionally heavy tools like pipe wrenches or sledgehammers. Mount the bar horizontally just above a flat shelf so that if a heavy tool does slip during an intense bump, it only drops an inch onto a solid surface rather than falling to the floor.

• Length: Available in 12-inch, 18-inch, and 24-inch configurations
• Pull Strength: Up to 20 lbs per inch
• Hardware: Mounting screws included

This magnetic bar is ideal for DIY-oriented RVers who want quick, organized access to their daily maintenance tools. It is not suitable for carbon fiber, plastic, or aluminum tools, which will not adhere to the magnetic strip.

Hose Support – Camco Sidewinder Support

Sewer hoses must maintain a steady downward slope from the RV waste outlet to the park sewer inlet to ensure proper drainage via gravity. Laying a sewer hose directly on the ground invites damage from sharp rocks, lawnmowers, and pests, while also creating flat spots where waste can pool. A sturdy, elevated support cradle protects the hose while maintaining the essential “waterfall” flow angle.

The Camco Sidewinder Support is the industry standard due to its lightweight, flexible accordion design that easily curves around obstacles. Constructed from all-plastic materials, it will not rust or corrode when exposed to harsh chemicals, UV rays, or black water spills. The deep cradles hold the sewer hose securely in place without the need for frustrating straps or ties, even when subjected to sudden pressure surges during tank dumping.

This support compresses down to a compact footprint for easy storage, but it must be rinsed thoroughly before collapsing to prevent grit from locking up the plastic hinges. Choose a length that matches your standard sewer hose setup; a 15-foot support is generally the sweet spot for most RV park hookups.

• Available Lengths: 10-foot, 15-foot, 20-foot options
• Material: Heavy-duty, rust-proof plastic
• Collapse Size: Compresses down to under 10 inches for storage

This support is a non-negotiable tool for full-time RVers who utilize full hookup campsites regularly. It is unnecessary for boondockers who only dump at dedicated dump stations before heading out to off-grid locations.

Storage Strap – Wrap-It Heavy Duty Strap

Heavy-duty 30-amp and 50-amp shore power cords are thick, heavy, and incredibly difficult to keep neatly coiled without assistance. Utilizing cheap zip ties or flimsy twist ties leads to frustration, as they break easily under the weight and tension of cold cables. A dedicated, high-strength wrap keeps these massive cords tightly bundled, preventing them from unraveling into an unmanageable bird’s nest in transit.

Wrap-It Heavy Duty Storage Straps are engineered with rugged industrial-grade nylon and a weatherproof hook-and-loop closure that holds up to 50 pounds of static weight. They feature a rust-resistant grommet at the top, allowing you to hang heavy coiled cords, ropes, or hoses from utility hooks mounted on your compartment walls. This simple addition lifts heavy cords off the floor, dramatically increasing your usable floor space.

These straps are sold in multi-packs with various sizes; the large and extra-large sizes are required for heavy 50-amp cords, while medium straps work perfectly for 50-foot extension cords or fresh water hoses. Over time, dirt and dog hair can clog the hook-and-loop material, so a quick brush-out may be required to maintain maximum holding strength.

• Material: Heavy-duty nylon with polypropylene hook-and-loop
• Weight Capacity: Up to 50 lbs
• Grommet: Rust-proof brass or stainless steel

These straps are perfect for anyone looking to organize heavy electrical cords, air hoses, or towing cables vertically. They are not required for small, lightweight household extension cords, which can be managed with simpler, cheaper fasteners.

Battery Box – NOCO Commercial Battery Box

RV house batteries are often located in exterior compartments or on the A-frame tongue, exposing them to road debris, moisture, and extreme temperature swings. Acid leaks or terminal short circuits can cause catastrophic damage to your rig’s frame or surrounding gear. A rugged, protective enclosure isolates these power sources, containing any potential leaks and preventing accidental tool contact with live terminals.

The NOCO Commercial Battery Box is built to withstand extreme environments, molded from an impact-resistant plastic copolymer that remains flexible down to negative 20 degrees Fahrenheit. It features a reservoir bottom designed to safely collect and isolate spilled battery acid, protecting your RV’s chassis from corrosion. The secure-fit lid includes molded entry ports for heavy-gauge battery cables, keeping them organized while preventing water intrusion.

Ensure you select the correct box size to match your battery group size (such as Group 24, 27, or 31), allowing extra room if you plan to upgrade to larger lithium-iron-phosphate (LiFePO4) batteries in the future. The box must be securely bolted down to the frame or compartment floor to prevent movement while driving.

• Material: Impact-resistant, acid-resistant plastic copolymer
• Certifications: Meets USCG Code of Federal Regulations (CFR 183.420)
• Ventilation: Built-in ventilation ports for lead-acid gas release

This box is critical for RVers running traditional lead-acid or AGM batteries in exposed locations or shared compartments. It is less critical for sealed lithium batteries mounted inside a climate-controlled, dedicated interior power closet.

Utility Hook – Command Outdoor Utility Hooks

The upper wall space of an RV compartment is rarely utilized, leaving a massive volume of air empty while the floor remains overcrowded. Hanging lightweight, frequently used items like keys, holding tank wrenches, gloves, and dog leashes gets them out of the way while keeping them visible. This eliminates the need to dig through deep bins for small, everyday items.

Command Outdoor Utility Hooks provide a damage-free hanging solution specifically designed to withstand the harsh outdoor elements. Unlike standard indoor adhesive strips that fail under humidity or extreme temperatures, these outdoor strips utilize a water-resistant, UV-resistant adhesive that holds strong from negative 20 to 125 degrees Fahrenheit. They can be mounted to plastic, metal, or painted fiberglass surfaces without drilling a single hole in your rig’s wall.

Proper surface preparation is key to ensuring a long-lasting bond; clean the mounting area thoroughly with rubbing alcohol and allow it to dry completely before applying the adhesive strip. Respect the weight limits marked on the packaging, as overloading a hook will cause it to release prematurely during a bumpy drive.

• Weight Capacity: Options ranging from 1 to 5 lbs per hook
• Temperature Range: -20°F to 125°F
• Adhesive: Weather-resistant, damage-free removal strips

These hooks are perfect for lightweight organization in rented RVs or for owners who want to avoid drilling holes in their compartment walls. They are not suitable for heavy tools, jacks, or thick electrical cables.

Managing Weight Distribution in RV Bays

Loading your RV bays without considering weight distribution can severely degrade your rig’s handling, fuel economy, and tire wear. Placing too much weight in the far rear compartments can create a lever effect, reducing the weight on your tow vehicle’s rear axle or causing dangerous trailer sway. Conversely, overloading the front pass-through bay can exceed your vehicle’s tongue weight rating or pin weight limit.

To maintain optimal stability, aim to place your heaviest items (like generators, heavy toolkits, and bulk water containers) as low as possible and as close to the RV’s axles as your layout permits. This approach keeps your rig’s center of gravity low, reducing body roll during high-speed cornering and mitigating the impact of strong crosswinds.

Always consult your RV’s federal placard to understand your Cargo Carrying Capacity (CCC) and never exceed your Gross Vehicle Weight Rating (GVWR). Periodically visiting a certified CAT scale with your rig fully loaded for a trip is the only way to verify that your wheel-by-wheel weight distribution remains within safe operating limits.

Keeping Exterior Compartments Dry and Clean

RV exterior compartments are constantly exposed to road spray, dust storms, and temperature-induced condensation. Over time, trapped moisture can rot wood paneling, rust tools, and foster toxic mold growth. Preventing this environmental damage requires a proactive approach that starts with maintaining your compartment seals and ends with proper interior ventilation.

Regularly inspect the rubber bulb seals around your compartment doors for cracks, compression set, or tears, replacing any damaged sections immediately to block road water. Applying a high-quality silicone slide-out lubricant to these seals twice a year keeps them pliable and prevents them from sticking to the metal frame in freezing temperatures.

For active moisture control, place renewable dehumidifier pots or silica gel packs inside your closed compartments to absorb ambient humidity. Whenever you pack up in the rain, make a point to dry off wet hoses and leveling blocks before sliding them into storage, or utilize breathable mesh bags to let them air-dry as you travel to your next destination.

Conclusion

Getting your RV’s exterior bays organized is more than just an aesthetic upgrade; it directly translates to less setup stress and more time enjoying the destination. By choosing durable, task-specific gear and managing your weight distribution wisely, you build a mobile system that is both resilient and highly functional. Invest the time to dial in your layout now, and your future self will thank you at every campsite down the road.
