Maximizing Your RV Exterior Storage Space

Exterior RV storage bays—often referred to as the “basement”—are the backbone of full-time mobile life. Unlike a traditional home basement, these compartments must house heavy-duty utilities, outdoor gear, and daily setup essentials in a highly vibrating, temperature-shifting environment. Throwing items into a bay loose is a recipe for damaged gear, wasted space, and immense frustration on travel days.

Maximizing this space requires shifting from horizontal thinking to vertical planning. Most RV basements are cavernous but lack built-in shelving, leaving vast amounts of unused headspace above a pile of cluttered gear. By utilizing walls, ceilings, and heavy-duty slide systems, every cubic inch becomes accessible without requiring a complete excavation to find a simple water pressure regulator.

Storage Bin – Rubbermaid ActionPacker 24-Gallon

Loose gear in a moving RV behaves like cargo on a storm-tossed ship. A dedicated heavy-duty storage bin corrals miscellaneous items like leveling blocks, wheel chocks, and spare parts, preventing them from sliding around and damaging sensitive RV plumbing or wiring. Without containment, small items inevitably migrate to the hardest-to-reach center of the pass-through bay.

The Rubbermaid ActionPacker 24-Gallon is a top choice for mobile storage because of its near-indestructible construction. Unlike cheap, brittle plastic bins that crack during cold-weather travel, this bin features an impact-resistant frame and a heavy-duty lid that can double as a step stool or work surface. The robust, lockable latches stay secure even when bouncing down washboard wash tracks.

• Capacity: 24 Gallons
• Dimensions: 26.5″ L x 19.3″ W x 17.4″ H
• Material: High-density polyethylene
• Best Uses: Leveling blocks, heavy hand tools, recovery gear

When planning your layout, measure the door opening of your storage bay, not just the interior dimensions. The ActionPacker’s flared lip can make for a tight squeeze through smaller baggage doors. This bin is perfect for full-timers needing rugged, stackable storage for heavy gear, but it may be overkill if you only need to store lightweight items like extra blankets or seasonal clothing.

Sliding Tray – MorRyde Sliding Cargo Tray CF54

Deep pass-through storage bays are a blessing and a curse. While they hold an immense amount of gear, retrieving items from the center of the bay usually involves crawling on hands and knees or using a makeshift reaching hook. A sliding cargo tray solves this accessibility crisis by bringing the entire contents of your basement out into the open air.

The MorRyde Sliding Cargo Tray CF54 stands out for its robust build quality and effortless operation. Built with commercial-grade ball-bearing slides, it allows you to pull out up to 800 pounds of gear with one hand. The tray slides out from both sides of the RV, ensuring that no item is ever buried out of reach.

• Weight Capacity: 800 lbs
• Extension: Two-way travel (slides out either side)
• Construction: Heavy-duty steel with a durable powder coat
• Fitment: Fits most standard pass-through compartments

Be aware that installing this tray will consume about three inches of vertical clearance in your bay and adds significant dry weight to your rig. You must securely bolt the unit into the floor joists of your basement to prevent tipping when fully extended. This is a must-have upgrade for diesel pushers and large fifth-wheels, but owners of lightweight travel trailers should carefully weigh the payload trade-offs.

Hose Reel – MorRyde Easy Reel Hose Spool REEL56

Freshwater hoses are notoriously difficult to manage, especially in cold weather when the plastic stiffens. They kink, leak residual water into the storage bay, and quickly unravel into an unmanageable mess. A dedicated reel keeps the hose compact, protects the fittings from dirt, and simplifies the daily hookup process.

The MorRyde Easy Reel Hose Spool REEL56 is engineered specifically for the tight confines of RV utility bays. It features a smooth-spinning crank mechanism and a sturdy steel frame that can be mounted to the floor or a sidewall. This design allows you to neatly spool up to 50 feet of drinking water hose in seconds without getting your hands dirty.

• Hose Capacity: Up to 50 feet of 5/8″ hose
• Mounting Options: Wall or floor mount
• Material: Powder-coated steel
• Dimensions: 13.5″ W x 12.5″ D x 19″ H

Before purchasing, verify that your utility bay has the clearance for the hand crank to rotate freely. It is critical to drain the hose completely before reeling it in to avoid pooling water inside the storage compartment. This reel is an excellent investment for anyone using traditional heavy-duty rubber or hybrid drinking hoses, but it is unnecessary if you rely solely on collapsible fabric hoses.

Utility Bag – Camco RV Hose and Cord Organizer

When you aren’t using a mechanical reel, storing electrical cords, coaxial cables, and auxiliary hoses together leads to a giant, tangled knot. More importantly, keeping your drinking water gear strictly isolated from sewer or gray water accessories is a fundamental safety practice. Utility bags offer a soft-sided, space-saving solution to keep these systems separate and clean.

The Camco RV Hose and Cord Organizer bags use a simple, color-coded system to prevent cross-contamination. Blue bags are reserved for fresh water, yellow for electrical cords, and black for sanitation or black-tank flush hoses. The bags feature a durable mesh top that allows wet hoses to breathe and dry out, preventing mold and mildew buildup inside the storage bay.

• Bag Types: Color-coded (Blue/Yellow/Black)
• Material: Heavy-duty fabric with breathable mesh sides
• Handle: Integrated reinforced carrying strap
• Included Accessories: Barrel lock drawstrings

These bags are highly flexible, meaning they can squeeze into odd-shaped corners where rigid bins cannot fit. However, because they are soft-sided, they cannot be stacked directly on top of each other without collapsing. They are perfect for full-timers looking for a budget-friendly, highly organized way to store secondary hoses, shore power cords, and electrical dogbone adapters.

Mounting Clamp – Quick Fist Original Clamp 10010

Long, awkward items like brooms, shovels, and slide-out toppers support poles often end up rolling around on the floor of a storage bay. This not only wastes valuable floor space but also risks damaging more fragile gear during transit. Mounting clamps allow you to utilize the unused vertical wall and ceiling space of your compartments to suspend these tools out of the way.

The Quick Fist Original Clamp 10010 is a favorite among overland builders and RVers alike due to its heavy-duty, UV-resistant rubber construction. Unlike metal brackets that rust or cheap plastic clips that snap under tension, these clamps hold items securely in place despite heavy road vibrations. They adjust easily to grip objects ranging from 1 inch to 2.25 inches in diameter.

• Holding Capacity: Up to 25 lbs per clamp
• Grip Range: 1″ to 2.25″ diameter
• Material: Heavy-duty, UV-resistant transportation-grade rubber
• Package Quantity: Sold in pairs

Installation requires screwing the clamps directly into the studs or backing material of your RV bay walls. Make sure to locate a secure backing plate or use hollow-wall anchors if mounting to thin luan panels. These clamps are ideal for securing tools you need to grab quickly, such as emergency tire irons or campsite maintenance gear.

Cargo Bar – Keeper 05059 Ratcheting Cargo Bar

No matter how neatly you pack your storage bins, a single sharp turn or sudden stop can send everything sliding into a disorganized heap. A cargo bar acts as a temporary wall, partitioning your storage bay into manageable sections. It holds heavy bins, coolers, and gear bags firmly in place without the need for permanent screws or tracks.

The Keeper 05059 Ratcheting Cargo Bar is an exceptional choice due to its rugged steel construction and precise ratcheting mechanism. It easily adjusts from 40 to 70 inches, making it compatible with almost any travel trailer or fifth-wheel pass-through bay. The large rubber end pads provide a solid grip without leaving scuff marks or damaging the compartment walls.

• Adjustment Range: 40″ to 70″
• Tension Type: Heavy-duty ratcheting mechanism
• End Pads: Non-marring rubber
• Material: Powder-coated steel

When using a ratcheting cargo bar, moderation is key. It is easy to apply too much pressure and bow the lightweight interior walls of an RV utility bay; tighten it just enough to snug the rubber pads against the sides. This tool is perfect for separating wet gear from dry storage, or keeping heavy battery boxes from shifting during travel.

Organizer Panel – Wall Control Steel Pegboard

Traditional fiberboard pegboards quickly disintegrate when exposed to the humidity and temperature swings of an outdoor RV storage bay. Yet, having a vertical wall of tools is the ultimate way to keep screwdrivers, wrenches, and tape rolls organized and visible. A steel pegboard panel provides a durable, vibration-proof backing to mount your most frequently used maintenance tools.

The Wall Control Steel Pegboard is twenty times stronger than traditional pegboard and will not warp, rust, or tear over time. Its unique design accepts both traditional 1/4-inch pegs and specialized slotted hooks, which stay locked in place much better during travel. The pre-mounted flange on the sides makes installation easy by keeping the peg holes spaced perfectly off the wall.

• Material: 20-gauge steel with powder-coat finish
• Hook Compatibility: Standard 1/4″ pegs and Wall Control slotted hooks
• Dimensions: Available in various sizes (commonly 16″ x 32″ panels)
• Color Options: Multiple colors to match utility bay aesthetics

To prevent tools from rattling off the hooks while driving down the highway, use locking pegs or wrap small bungee cords across the face of the board. Ensure you mount the panel directly to the aluminum framing of your RV basement for maximum load capacity. This setup is perfect for DIY-minded full-timers who maintain their own rigs and need instant access to tools.

Utility Bucket – Camco Collapsible 5-Gallon

A five-gallon bucket is an indispensable tool for RV maintenance, gear washing, and emergency grey water management. However, a rigid plastic bucket is a massive space-hog in an exterior storage bay, taking up valuable real estate even when completely empty. A collapsible utility bucket provides all the utility of a standard bucket but folds completely flat when not in use.

The Camco Collapsible 5-Gallon Bucket is a highly durable solution constructed from heavy-duty, waterproof fabric. It features a rigid rim and base that allow it to stand upright even when fully loaded with water. When empty, it collapses down to a mere 2.25 inches thick and fits into its own zippered storage sleeve.

• Capacity: 5 Gallons
• Collapsed Height: 2.25″
• Material: Heavy-duty PVC-coated polyester
• Included Accessories: Zippered storage bag

While this bucket is incredibly tough, avoid using it to store sharp metal tools or heavy, abrasive hardware that could puncture the inner lining. Always rinse and thoroughly dry the fabric before folding it away to prevent mildew growth. This is an essential gear upgrade for any RVer, particularly those in smaller rigs like class B vans or teardrop trailers where space is at an absolute premium.

Label Maker – Brother P-touch PT-D210 Maker

An organized storage bay is only useful if everyone in the RV knows where things belong. In the heat of a rainy-day setup, squinting into identical plastic bins to find a water splitter is frustrating and time-consuming. Clear, durable labels on every bin, bag, and utility connection eliminate guesswork and keep your storage system functioning long-term.

The Brother P-touch PT-D210 is a highly reliable option for creating durable, weather-resistant labels on the fly. It utilizes laminated TZe tapes, which are designed to withstand extreme temperatures, moisture, and UV exposure without peeling or fading. The keyboard layout is intuitive, and the device offers pre-designed templates for quick labeling of common utilities.

• Tape Compatibility: Brother TZe tapes (up to 12mm width)
• Power Source: 6 AAA batteries or optional AC adapter
• Display: Easy-view graphical display
• Memory: Saves up to 30 custom label templates

For best results in exterior bays, use the “extra strength adhesive” TZe tapes, which stick reliably to textured plastic bins and metal panels. Ensure the application surface is clean and free of road grime or oils before applying the label. This tool is a game-changer for full-time families or couples who share setup duties and need a standardized system.

Storage Box – Lippert Underchassis Storage Box

Sometimes, no matter how much you organize, you simply run out of room inside your standard exterior storage bays. The area beneath your RV’s chassis is often a vast, unused expanse of space that can be tapped into for cargo storage. An under-chassis storage box mounts directly to the frame rails, reclaiming this dead space for seasonal or rarely used items.

The Lippert Underchassis Storage Box utilizes a smart, slide-out bin design that mounts securely between your RV’s frame members. Constructed from heavy-duty, impact-resistant plastic, it is completely weatherproof and keeps road debris and moisture away from your gear. The sliding mechanism allows you to pull the storage bins out from either side of the coach for easy access.

• Mounting Location: Underneath the RV chassis, attached to frame rails
• Material: Corrosion-resistant steel frame with heavy-duty plastic bins
• Capacity: Varies by model (standard dual-bin systems hold substantial cargo)
• Security: Lockable lid latch system

Installing this system requires drill-mounting directly into the steel frame of your RV, which demands proper safety gear and basic mechanical skills. Keep in mind that this box will reduce your overall ground clearance, so it is not recommended for off-grid overland rigs that frequently traverse rough terrain. It is the ultimate upgrade for highway-bound fifth-wheelers who need a home for spare tires, sewer hoses, or seasonal outdoor gear.

How to Weight and Balance Your RV Storage Bays

Organizing your storage bays isn’t just about convenience—it is a critical safety practice. Overloading your RV or distributing weight poorly can lead to tire blowouts, poor handling, and structural damage. Every RV has a strict Cargo Carrying Capacity (CCC) that must never be exceeded, and how you distribute that cargo weight matters immensely.

As a rule of thumb, place your heaviest items (like tools, heavy-duty electrical cords, and leveling blocks) as low as possible and close to the center axle line. Placing too much weight in the very rear of a travel trailer can cause dangerous trailer sway, while overloading the very front can exceed your tow vehicle’s hitch weight rating. Keep lightweight items, such as camp chairs and outdoor mats, in the outer edges of your storage compartments.

Regularly visit a certified CAT scale to check your axle weights and ensure your rig is balanced side-to-side. An unbalanced RV can cause uneven tire wear and put excessive strain on your suspension components. Take the time to weigh your rig fully loaded for travel, and adjust your basement storage layout accordingly to ensure a safe, smooth towing experience.

Taking the time to organize your RV’s exterior storage bays pays dividends every single time you arrive at or depart from a campsite. By utilizing heavy-duty bins, vertical mounts, and smart under-chassis options, you can turn a chaotic basement into a model of off-grid efficiency. Invest in these high-quality organizational tools today and experience the peace of mind that comes with a perfectly balanced, clutter-free rig.
