Hide Gear in Motorhomes (DIY RV Storage Hacks)
To store gear out of sight in a motorhome, start with an existing cabinet or a small, purpose-built compartment that does not block safety equipment, vents, or service access. Check weight limits and hidden systems before drilling. Anchor the compartment to confirmed structure, add a positive latch, and recheck axle weights, airflow, and access when the build is complete.
Have you found a useful nook in your motorhome, only to wonder whether a furnace duct, wire, or pipe runs behind it? That pause is wise. A tidy storage project should keep everyday gear out of view without hiding safety equipment or creating a hazard on the road.
I plan RV storage around four checks: weight, structure, clearance, and access. The steps below help you choose a spot, build a secure compartment, and test it before travel. Any example dimensions are starting points for planning, not universal specifications; your vehicle and appliance manuals take priority.
Plan Storage Around Payload, Structure, and Safety Systems
Payload is the weight your motorhome can carry after accounting for the vehicle’s stated limits. Before choosing a storage spot, check the certification label and manuals for the gross vehicle weight rating (GVWR) and gross axle weight rating (GAWR). Include the compartment, hardware, and stored gear in your calculations.
Start by weighing the motorhome as it is usually loaded for travel. Get axle weights if possible, then compare each axle with its GAWR. Do not treat unused capacity on one axle as extra capacity for another. Total vehicle weight must also remain within GVWR.
Tire limits matter, too. Check each tire’s sidewall load and inflation limits, along with the vehicle placard’s cold-pressure instructions. Do not guess at tire pressure from the total vehicle weight. If your loaded weight approaches any limit, reduce cargo or ask a qualified RV weighing service or technician for guidance before adding storage.
| Storage option | Useful for | Main checks before building |
|---|---|---|
| Existing cabinet with a new divider | Light clothing, small personal items | Latch retention, shelf support, and nearby service access |
| Under-bed bin or drawer | Bulky, light gear | Bed mechanism, wiring or plumbing below, and safe anchorage |
| New shallow compartment | Items with a defined home | Framing, hidden systems, weight, ventilation, and appliance clearance |
| Exterior bay organizer | Outdoor gear | Bay load limits, door clearance, access to equipment, and secure retention |
A compartment’s apparent empty space is not proof that it is safe to use. RV walls and cabinets can conceal wiring, plumbing, tanks, structural members, or appliance parts. Inspect the area from both sides when possible, review available plans, and locate service panels before cutting or drilling.
Set a written limit for the gear you plan to store. Weigh the gear and proposed materials, then note where they will sit. Heavy items placed far behind an axle can affect axle loads differently from lighter items near the center. If you cannot verify the structure or weight impact, choose an existing storage space instead.
Check Access, Appliance Clearances, and Airflow
Clearance is the open space an appliance needs around it for safe operation and service. There is no single safe distance for every RV furnace, cooktop, or flue. Use the exact clearances in that appliance’s label and manual, and keep required access panels reachable.
An unused-looking cabinet may serve as a furnace return-air path, combustion-air opening, wiring junction, or service space. Blocking an air path can interfere with appliance operation; covering a service panel can prevent inspection or repair. Check the appliance documentation and the compartment itself before adding a wall, bin, or door.
Do not cover smoke, carbon monoxide (CO), or LP-gas detectors. Keep emergency exits and required safety equipment clear and usable. Leave electrical access panels, return-air grilles, and combustion-air openings open. If the manual is unclear about airflow or clearance, stop and ask the appliance maker or a qualified RV technician. A DIY compartment has no universal airflow rating.
Map the space before you cut
A simple survey reduces the chance of hitting a hidden system or blocking a needed opening. I mark the proposed compartment on painter’s tape first, then check its reach and door swing before any work begins.
- Find the appliance model and read its installation and service instructions.
- Locate visible wires, pipes, tanks, ducts, detectors, and service panels.
- Check both sides of the planned surface where access allows.
- Confirm the storage door will not block an exit or required equipment.
- Record existing axle weights and available payload for the loaded vehicle.
A stud finder may help locate framing, but it does not confirm that a drill path is clear of wires or pipes. Never drill blindly into a wall, floor, or cabinet. If you cannot confirm the route and mounting surface, do not make the hole.
Frame, Anchor, and Finish the Storage Compartment
Anchorage is the way a compartment connects to the motorhome’s structure. A screw in decorative paneling alone is not a reliable way to hold heavy gear during sudden braking. Confirm framing or a manufacturer-approved mounting point, then choose corrosion-resistant fasteners and supports rated for the load.
First decide what the compartment will hold and weigh it. Add the expected weight of the box, door, shelves, hardware, and contents. Use that total to select supports and fasteners with documented ratings. There is no universal load rating for RV cabinets, so do not assume that a household cabinet standard applies.
Build the box from material suited to the space and load; keep it as light as practical. A small, square frame is easier to anchor and check than an oversized enclosure. Round or cover exposed edges, and make sure drawers and doors cannot snag clothing or block nearby equipment.
Fit a positive latch that stays shut during travel. A magnetic catch or friction fit alone may not restrain contents when the vehicle stops suddenly. Match the latch and mounting points to the loaded door or drawer, and test them with the compartment packed. Do not use adhesive or unrated hardware as the only restraint for heavy gear.
Two planning examples
These are illustrative examples, not reports of tested vehicles. They show how the same storage goal can lead to different choices once weight, location, and service access are considered.
- Light clothing under a bed: A removable bin may be safer than a fixed drawer if the area has unverified wiring or plumbing. Keep the bed mechanism clear, secure the bin for travel, and weigh the packed load.
- Tools near a furnace cabinet: Do not enclose space that may serve the furnace or its service access. Move the tools to an existing exterior bay or another verified storage area, even if the first spot looks convenient.
Building on this, a removable organizer can be the better choice when the wall structure or hidden systems are uncertain. A fixed compartment makes sense only when you can confirm the mounting surface and preserve all required access and airflow.
Verify Loads, Latches, Ventilation, and Service Access
Verification means checking the finished storage under realistic conditions, not just confirming that it looks neat. Load the compartment as planned, test the latch, inspect clearances, and reweigh the motorhome if the added load could affect axle limits.
Use this final sequence before travel:
- Load and weigh: Include the compartment, hardware, and all stored gear. Confirm total weight is within GVWR and each axle is within its GAWR. Check tire limits and the placard’s cold-pressure instructions.
- Test the latch: Close the compartment fully and make sure the positive latch engages every time. Recheck it with the intended load inside. Do not rely on a loose door or unsecured bin.
- Check air and access: Confirm grilles, appliance openings, detectors, service panels, and exits remain clear. Compare appliance clearances with the label or manual.
- Inspect the finish: Protect sharp edges and repair any barrier or finish you disturbed, following the vehicle maker’s instructions.
- Recheck after travel: Look for loose fasteners, shifting contents, rubbing, or blocked access. Tighten or revise the storage before the next trip.
For electrical work, follow the motorhome maker’s instructions and the applicable requirements of NEC Article 551. NFPA 1192 may also apply to RV construction and use. The relevant edition and local requirements depend on the project and location, so confirm adopted rules with the authority having jurisdiction (AHJ). If the work affects wiring, appliances, or safety systems, consult a qualified RV professional.
Know when to stop
Do not proceed if you cannot identify a drill path, confirm a structural anchor, or preserve an appliance’s required clearance. Stop, too, if the project would cover a detector, exit, required safety item, or service panel. A smaller storage solution is preferable to a hidden hazard.
The safest DIY RV storage hack is often a well-secured organizer in an existing bay, not a new concealed cavity. Keep the added weight modest, the latch reliable, and maintenance access open. If the compartment changes how an appliance or electrical system operates, get qualified help before using it.
Frequently Asked Questions
These answers cover common choices when adding hidden or out-of-sight storage in a motorhome. Use them as planning guidance, then confirm the details against your vehicle and appliance manuals. If a limit, clearance, or mounting point is uncertain, ask the manufacturer or a qualified RV technician.
Where can I add hidden storage in a motorhome?
Start with an existing cabinet, bed base, or exterior bay. Check framing, hidden systems, appliance access, and weight limits before changing it.
Can I build a compartment beside an RV furnace?
Only if the appliance manual’s clearances, airflow needs, and service access remain intact. Do not enclose a space you have not inspected.
How do I know if an RV cabinet can hold heavy gear?
There is no universal RV cabinet load rating. Verify the structure and use supports and fasteners with documented ratings for the loaded mass.
Can I attach storage to thin paneling?
Do not rely on decorative paneling alone to restrain heavy gear. Fasteners should engage confirmed framing or a manufacturer-approved mounting point.
How do I keep stored gear from moving while driving?
Use a positive latch and secure the contents inside the compartment. Test the loaded door or drawer before travel; a friction fit alone is not enough.
Does added storage affect motorhome weight limits?
Yes. Count the compartment, hardware, and contents toward total vehicle and axle loads. Check GVWR, each GAWR, and the tire limits.
Can I cover an RV vent or return-air grille with a storage box?
No. Keep required return-air grilles, combustion-air openings, and appliance vents clear according to the appliance instructions.
Should I weigh the motorhome after building storage?
Weigh it when the added load could affect capacity. Compare total and axle weights with the vehicle’s GVWR and GAWR, and check tire limits.
Can I drill into an RV floor or wall for a storage mount?
Not blindly. Locate framing and check for wiring, plumbing, tanks, and appliances first. If the route is uncertain, do not drill.
Which rules apply to RV storage modifications?
Follow the motorhome maker’s instructions and confirm applicable NFPA 1192 and NEC Article 551 requirements with the local AHJ, especially for electrical work.
