9 Essential External Storage and Accessibility Upgrades for Full-Time RVers

Transitioning to full-time RV living quickly reveals that interior cabinet space is only half the storage equation. When bulky gear, muddy tools, and daily-use items clog your living quarters, the exterior of your rig becomes prime real estate. Upgrading your external storage and accessibility setups is not just about carrying more stuff; it is about reclaiming your indoor living space and making daily campsite setups effortless.

How to Assess Your RV Exterior Storage Capacity

Before purchasing a single bracket or bolt-on box, a systematic audit of the rig’s physical and weight capacities is essential. Every trailer or motorhome has a strict Cargo Carrying Capacity (CCC) listed on the federal tire sticker, which dictates how much total weight can be added. Overloading external mounts can dangerously alter the rig’s center of gravity and tongue weight, leading to severe towing instability or frame failure.

Map out the existing external footprint to identify unused zones. Look closely at the rear bumper (checking if it is a standard 4-inch square steel bumper or a lightweight decorative cover), the A-frame tongue area, the undercarriage, and the roof. Note how existing access doors swing open, as new gear must not block vital utility hatches, shore power connections, or slide-out paths.

Hitch Cargo Box – GearSpace 340 Cargo Carrier

Bulky, weather-sensitive gear like portable generators, extra fuel cans, and oversized camping chairs quickly overwhelm standard RV basement bays. A hitch-mounted cargo box solves this by relocating these heavy, dirty items to the rear of the rig, keeping fumes and grime outside the living space. This upgrade utilizes the vehicle’s rear receiver hitch to create a secure, weatherproof locker that moves with the vehicle without affecting overhead clearance.

The GearSpace 340 Cargo Carrier stands out because of its massive storage footprint and robust, rotomolded polyethylene construction. It supports heavy utility gear on a steel frame that slides backward on a telescoping arm, allowing access to rear doors or engine bays without unloading. Its aerodynamic capsule design reduces drag compared to boxy metal cages, and the secure dual-lock system keeps expensive gear safe.

• Capacity: 34 cubic feet
• Weight Limit: Supports up to 300 lbs of cargo
• Best For: Heavy utility gear, generators, and large camping equipment
• Key Feature: Telescoping slide-out frame for rear door clearance

Before buying, verify the rig’s tongue weight rating, as this carrier adds significant leverage to the rear hitch. The unit itself weighs roughly 135 pounds empty, meaning it requires a sturdy Class II or III 2-inch receiver and will reduce remaining cargo capacity accordingly. This carrier is perfect for full-timers hauling heavy utility gear, but it is too heavy for small rigs with low hitch capacities.

RV Entry Steps – LIPPERT SolidStep Triple Entry Step

Traditional bouncy, hanging RV steps are a recipe for instability and joint stress, especially when carrying heavy groceries or navigating camp in the dark. Upgrading to a ground-supported step system eliminates the springy motion that shakes the entire RV every time someone enters or exits. This simple change provides a residential-grade foundation that drastically improves accessibility and safety.

The LIPPERT SolidStep Triple Entry Step is the premier choice for this upgrade because it mounts directly to the door threshold and extends all the way to the ground. Featuring adjustable leg extensions with pivot feet, it adapts instantly to uneven campsite terrain to ensure a perfectly level, wobble-free climb. The top step is deeply recessed to give users plenty of foot room when transitioning out of the doorway.

• Step Count: Triple-step configuration (double and quad also available)
• Weight Capacity: 400 lbs
• Material: High-grade aluminum with steel brackets
• Key Feature: Adjustable legs for uneven terrain and extra-wide top step

Keep in mind that these steps fold upward directly into the door frame for travel. This means any loose dirt, mud, or rainwater on the steps must be swept off before folding them inside, or it will end up on the interior floor. This step is a must-have upgrade for full-timers prioritizing joint comfort and structural stability, though owners of ultra-low profile trailers should measure carefully to choose the correct height configuration.

Rooftop Cargo Box – Yakima SkyBox 16 Carbonite

Seasonal gear like snowboards, winter coats, sleeping pads, and extra bedding can sit unused for six months at a time, taking up prime cabinet space. A rooftop cargo box capitalizes on vertical real estate, moving lightweight, high-volume items completely out of the daily workflow. Utilizing the roof keeps the living area uncluttered while keeping seasonal essentials close at hand.

The Yakima SkyBox 16 Carbonite excels in this role with its aerodynamic storage profile and dual-sided opening mechanism, which allows access from either side of the rig. Its textured Carbonite lid resists UV degradation and scratches from low-hanging branches, while the secure latch system ensures the box is locked before hitting the highway. The internal stiffening struts make opening and closing smooth, even when standing on a ladder.

• Volume: 16 cubic feet of storage space
• Access: Dual-sided opening for versatile campsite access
• Material: Textured Carbonite made from up to 80% recycled material
• Key Feature: Tool-free quick-installation mounting hardware

Installation requires an existing roof rack or crossbar system on either your motorhome, travel trailer, or tow vehicle. Always measure the rig’s total height with the box installed to avoid catastrophic run-ins with low-clearance bridges and tree branches. This is the ultimate storage solution for active outdoor enthusiasts carrying lightweight, bulky gear, but it is not suitable for heavy toolboxes or generators due to roof weight limits.

RV Bike Rack – Swagman Dispatch RV Approved Platform

Standard bicycle racks are not built to withstand the violent vertical whipping motions that occur at the rear of a long travel trailer or motorhome. Using a non-RV-approved rack often leads to metal fatigue, broken welds, or lost bicycles on the interstate. An RV-rated platform rack keeps expensive bikes rock-solid, preventing them from rubbing against each other or the back wall of the coach.

The Swagman Dispatch RV Approved Platform is specifically engineered to handle the extreme forces of RV towing. It features a heavy-duty steel construction that carries two bikes securely by their wheels rather than their frames. The adjustable locking hooks slide down the center mast to clamp the frames tightly, while the wheel trays accommodate varying tire widths.

• Capacity: Carries 2 bikes up to 45 lbs each
• Hitch Compatibility: Fits standard 2-inch receivers only
• Tire Compatibility: Fits tires up to 3 inches wide
• Key Feature: RV-approved heavy-duty structural rating

Before purchasing, note that this rack requires a 2-inch receiver hitch and cannot be used with 1.25-inch adapters. The rack itself weighs about 47 pounds, so ensure the rear bumper hitch has the necessary tongue capacity to support the combined weight. It is the ideal choice for e-bike owners and commuter cyclists who need reliable security, but it is not designed for fat-tire bikes over 3 inches wide without purchasing separate trays.

Sewer Hose Carrier – Valterra EZ Hose Carrier

Stowing a wet, contaminated sewer hose inside a general storage compartment is a sanitation nightmare. A dedicated, sealed external carrier isolates waste management gear from clean campsite items like water hoses, electrical cords, and outdoor rugs. This simple addition keeps unpleasant odors and bacteria entirely outside the RV’s living envelope.

The Valterra EZ Hose Carrier is the industry standard because of its telescoping design, which adjusts to fit almost any rig width. Made of heavy-duty, UV-protected black plastic, it features easy-open threaded caps on both ends with integrated ventilation holes that allow damp hoses to dry naturally, preventing mold growth. The caps also feature padlock loops to prevent tampering or accidental opening on bumpy dirt roads.

• Length Range: Telescopes from 50 inches to 94 inches
• Diameter: 4.25-inch inner diameter to fit standard fittings
• Mounting: Includes heavy-duty mounting brackets and self-tapping screws
• Key Feature: Ventilated caps to prevent mold and mildew build-up

Installation requires mounting the brackets to the RV frame or bumper using the included self-tapping screws or heavy-duty zip ties. Position the carrier high enough to avoid scrape hazards when navigating steep transitions, but low enough for easy access at the dump station. This is a non-negotiable upgrade for any RVer using multi-section sewer hoses with bulky elbow fittings, but ensure specific hose fittings fit the 4.25-inch inner diameter before purchasing.

Telescoping Ladder – Xtend & Climb Pro Series 785P

A reliable ladder is non-negotiable for full-timers who must regularly clear leaves off slide-outs, inspect roof seals, and clean solar panels. However, carrying a standard A-frame ladder takes up immense space, while fixed rear ladders are often flimsy and prone to water-intrusion leaks at their mounting points. A high-quality telescoping ladder offers the height of an extension ladder but shrinks down to fit in a fraction of a basement bay.

The Xtend & Climb Pro Series 785P is the benchmark for safety and compact storage, collapsing down to a highly packable size while extending to a full, usable reach. Made from aerospace-grade aluminum, it is ANSI/OSHA rated for safety and features slip-resistant feet for secure placement on dirt or concrete. Its patented True-Telescoping technology allows it to lock smoothly at one-foot increments, making it highly adaptable to varying rig heights.

• Extended Height: 15.5 feet (equivalent to a 19.5-foot reach)
• Closed Height: 36.5 inches for easy basement storage
• Weight Rating: ANSI/OSHA rated for 250 lbs
• Key Feature: Angled thumb release system for safe, pinch-free closure

While highly durable, telescoping ladders require proper maintenance; keep the stanchions free of grit and oil to prevent sticky operation. Users must pay close attention to hand placement during closure to avoid pinching fingers, although this model features a controlled, slow-down retraction system to minimize risk. It is a critical investment for anyone with a rig lacking a built-in ladder or those who refuse to trust cheap, uncertified knockoffs.

RV Assist Handle – Stromberg Carlson Lend-A-Hand Rail

Standard factory-installed entry handles are often small plastic straps that offer minimal leverage and feel flimsy under weight. Upgrading to a large, rigid assist rail provides a continuous, sturdy grab point that extends far outward from the doorway, dramatically reducing the risk of slips or falls on wet days. This simple exterior addition is especially vital when negotiating steep, ground-supported steps or carrying bulky loads.

The Stromberg Carlson Lend-A-Hand Rail is the premier choice due to its heavy-duty aluminum construction and ergonomic foam grip that spans the entire length of the bar. It locks securely into three positions: open for use, folded flat to the left, or folded flat to the right, which also serves to help keep the RV door closed while in transit. The extra-large loop design provides support from the bottom step all the way through the threshold.

• Material: Heavy-duty aluminum tubing with foam grip overlay
• Locking Positions: Three distinct lock positions (left, right, open)
• Dimensions: 29.5 inches long by 14.5 inches wide
• Key Feature: Large, continuous loop design for multi-level support

Installation requires mounting the brackets directly into the structural aluminum or wood studs beside the entry door, not just into the thin fiberglass siding. Always apply a high-quality sealant behind the mounting brackets to prevent moisture from penetrating the wall cavity. This handle is highly recommended for RVers with kids, pets, or limited mobility, but owners must ensure it does not cover porch lights or window vents when folded flat.

Underchassis Storage – Lippert Underchassis Storage Bin

The space between an RV’s chassis frame rails and the road is often completely wasted, yet it is the single best location to store heavy, flat gear. Utilizing this lower zone keeps the overall center of gravity down, which dramatically improves towing stability compared to packing heavy items high up. Underchassis bins turn this dead space into a clean, slide-out drawer system for dirty gear like leveling blocks and wheel chocks.

The Lippert Underchassis Storage Bin utilizes a clever steel rail system that mounts directly to the frame, holding two durable, molded plastic bins that slide out from either side of the rig. Each bin features a high weight capacity and includes a weather-resistant lid to keep road grime, water, and salt off your equipment. It keeps essential setup gear easily accessible right where you need it—down low near the tires and jacks.

• Weight Capacity: Holds up to 100 lbs per bin (200 lbs total)
• Materials: Heavy-duty molded plastic bins with steel framing rails
• Access: Slide-out access from either side of the RV
• Key Feature: Dual bins with weather-resistant storage lids

Before installing, check that the rig has sufficient ground clearance; this system is best suited for travel trailers and fifth wheels with high-clearance frames. You will need to drill into the chassis frame to secure the mounting brackets, which requires a heavy-duty drill and cobalt bits. This upgrade is perfect for full-timers looking to completely clear out their main pass-through bays, but it is not recommended for low-slung trailers that frequent rough, rutted forest roads.

Bumper Storage Tray – Mount-n-Lock GennyGo

Most stock travel trailer bumpers are notoriously weak, made of thin 14-gauge steel with minimal welding that can easily shear off when subjected to the bouncing weight of a generator or bike rack. A bumper storage tray system solves this structural weakness while adding flat, heavy-duty platform space at the rear of the rig. This allows you to carry heavy utility items safely without risking a catastrophic bumper failure on the highway.

The Mount-n-Lock GennyGo system is the standout choice because it couples an all-aluminum, rust-free storage tray with patented steel SafetyStruts bumper brackets. These brackets bolt directly to the RV’s main frame rails, transferring the weight of the bumper load away from the weak factory welds and increasing overall capacity. The modular trays are pre-drilled, allowing you to mount generators, fuel cans, or storage boxes with standard ratchet straps.

• Load Capacity: Up to 400 foot-pounds of cargo weight
• Material: Lightweight, rust-free high-grade aluminum tray
• Reinforcement: Includes steel SafetyStruts to prevent bumper detachment
• Key Feature: Modular tray design can be paired for larger footprints

Ensure you visually inspect your factory bumper welds for existing rust or cracks before installation. While the SafetyStruts reinforce the connection to the frame, they cannot salvage a completely rusted-through steel tube. This tray system is a phenomenal upgrade for boondockers carrying heavy inverter generators or extra fuel, but users must be mindful not to exceed the overall rear weight limits of their trailer.

Weight Distribution and Safety Rules for RV Storage

Adding external storage solutions changes the dynamics of how an RV handles on the road. The most critical rule of RV storage is maintaining proper weight distribution, specifically keeping 10 to 15 percent of a travel trailer’s total weight on the hitch (tongue weight) and 15 to 25 percent for a fifth wheel (pin weight). Concentrating too much heavy gear on the rear bumper or hitch carrier lightens the tongue, which is the primary cause of dangerous, uncontrollable trailer sway (yaw) at highway speeds.

Always place the heaviest items—such as toolkits, generators, and heavy leveling blocks—as close to the axles as possible, ideally in underchassis bins or low pass-through compartments. Reserve high or extreme-end storage points, like rooftop boxes or rear bumpers, for high-volume, low-weight items like sleeping bags, empty water jugs, or aluminum ladders. Every time you add a new external accessory, run your rig through a certified CAT scale to verify that you are not exceeding individual axle weight ratings or your vehicle’s GVWR.

Remember that leverage amplifies weight; a 100-pound generator sitting on a hitch carrier three feet behind your rear bumper exerts far more force on your frame than that same 100 pounds sitting directly inside a rear storage bay. Regularly inspect all mounting brackets, hitch pins, and safety straps for signs of metal fatigue, loosening bolts, or rust. Taking these safety precautions ensures your new storage upgrades make your travels easier without compromising safety on the road.

Balancing Accessibility Needs with Rig Aerodynamics

Every external addition to an RV changes its wind profile, which directly impacts your tow vehicle’s fuel economy or your motorhome’s range. Large, boxy structures mounted on the roof or sides create massive aerodynamic drag, forcing the engine to work harder and increasing wear on transmission systems. Finding the sweet spot between easy-access storage and a streamlined profile requires strategic placement of your upgrades.

Position sleek, low-profile accessories like the Yakima SkyBox on the roof, aligning them with the natural airflow of the front cap. Avoid mounting square crates or bulky items on the roof where they act as wind sails; instead, tuck those into rear-mounted hitch boxes like the GearSpace, which sit in the low-pressure draft zone behind the rig. Underchassis storage is another aerodynamic winner, as it utilizes the existing under-car airflow without adding any frontal area to the vehicle.

Accessibility should be prioritized for items used during daily setups, such as sewer hoses, leveling blocks, and entry steps, which must remain at ground level for quick deployment. Seasonal or emergency gear can be relegated to high-altitude or deep slide-out storage zones that take longer to access. By balancing aerodynamic efficiency with logical tool placement, you create a rig that is both economical to drive and effortless to set up.

Conclusion

Maximizing your RV’s external storage and accessibility is the key to thriving in a mobile lifestyle over the long haul. By shifting bulky, dirty gear to the exterior and upgrading to stable entry systems, you reclaim your indoor living space for comfort and relaxation. Invest in high-quality, task-specific upgrades to ensure your rig remains safe, efficient, and ready for any adventure.
