The space you’re looking for isn’t hiding. It’s just being used for something else.
A wall that holds a picture. The cavity inside a bench seat. The gap behind a drawer. The two inches between the bed frame and the wall rib. In a small motorhome, every one of those is potential storage — if you know where to look.
Here’s how to find it.
The Mindset Shift: Space Is Everywhere
Most people organize by buying containers and filling cabinets. A smarter approach is to look at every surface and cavity differently.
That means asking uncomfortable questions. Does this bench need to be solid? Can this wall hold a rail? Is that panel hiding a void? The answers usually reveal more space than you expect.
A van builder recently discovered this by cutting into the metal structural ribbing of a cargo van. By creating recessed headboards in the wall cavities, they gained two inches of clearance on each side — four inches total. That extra space made the difference between a cramped bed and a comfortable one .
Two inches sounds small. In a motorhome, it’s everything.
Look Behind the Walls
The panels in your motorhome aren’t always flush against the exterior skin. There’s often a gap — sometimes an inch, sometimes several — between the interior paneling and the structural framing.
The under-sink secret compartment. One Airstream owner found a hidden storage space behind a plywood wall under the sink, next to the garbage can. The wall was structural, but by reinforcing it with a wooden platform and a slide-out tray, they created a pull-out space for their espresso machine. They also used repurposed aluminum dryer vent cylinders to store plastic bags, with the cylinders extending all the way to the wall .
The 2-inch trick. The van builder who created sunken headboards did it by cutting custom plywood sections and recessing them directly into the wall cavities between metal studs. It was “an absolute pain to align,” but the payoff was four inches of total extra space — enough to stretch out comfortably .
If you’re willing to cut, reinforce, and rebuild, the walls can give you more than you think.
The Dead Zones You’re Ignoring
Some spaces are too awkward to use for normal storage. That’s exactly why they’re valuable.
Behind the seats. A narrow rack behind the driver or passenger seat holds maps, jackets, and a small tool roll. It’s dead space in most builds, but it becomes a high-use storage lane with almost no downsides .
The luton or overhead shelf. A converted high-top Fiat Doblo had a shelf above the front seats measuring about 120 x 50 x 30cm, tapering toward the curved roof. The owner used it for sleeping bags and “chuck things out of the way” items. Forum members suggested packing cubes and Really Useful boxes to create order. One owner noted that using boxes in the luton meant the boxes could be brought down and used as bed extenders when parked — serving three purposes at once .
The gap between the bed and the wall. A properly designed under-bed storage system doesn’t just hold bins. It can extend the bed itself. One forum member used luton boxes to bridge the gap left by forward-sliding seats, gaining about 10 inches of additional bed length while keeping the contents accessible .
Storage You Can Build In
Some of the best storage solutions require a drill and an afternoon. These are the ones worth the effort.
Wall Rails and MOLLE Panels
Wall tracks and MOLLE-style panels mount to solid structure — ribs, studs, or reinforced points. They hold pouches, hooks, bins, and quick-release mounts. The key is keeping the “daily grab” zone near the door: flashlights, first-aid, tire tools, gloves .
Shelving in Closets
Closets in motorhomes are often too deep and too narrow to be useful. One couple solved this by building lightweight metal shelving units inside their bedside closets. The units were wider than the closet doors, so they had to be assembled in place — a frustrating process involving counting rings on legs and dropping plastic supports repeatedly. But the result was usable shelves where only hanging space existed before .
Under-Bed Garage with Drawers
The under-bed area offers the biggest storage payoff. Raise the bed platform just enough to fit standardized bins or drawers, then add locking slides or latches to keep them closed on rough roads .
Divide the garage by mission. One side for “dirty gear” — leveling blocks, hoses, muddy items. One side for “clean gear” — clothing, pantry overflow, spare bedding. Add a side hatch for quick-grab items. A hatch beats unloading three bins to reach one piece of gear .
The Products That Create Space
You don’t always need to build. These items carve out space where none seems to exist.
Collapsible and nesting items. Bowls that flatten. Measuring cups that stack. Laundry baskets that collapse. A collapsible colander takes almost no space when stored .
Tension rods. In cabinets, they keep plates and cutting boards from shifting. In the bathroom, they create a hanging space for towels or wet gear .
Over-the-door organizers. A shoe organizer on the bathroom door holds toiletries, first aid supplies, and sunscreen. One organizer replaces an entire cabinet’s worth of clutter .
Magnetic strips. Mount one on the wall for knives, spices, or small tools. It frees drawer space and keeps frequently used items visible .
Slide-out trays and drawers. Deep cabinets become far more usable with pull-out trays. You access the back without unloading the front .
Microfiber towels. They replace bulky bath towels, take up a fraction of the space, and dry in minutes draped over a mirror .
Comparison Table: Hidden Storage Solutions

| Under-Sink Compartment | Behind false wall | Moderate | Small, specific | $10–$30 |
| Closet Shelving | Deep closets | Moderate | Multiplies usable height | $20–$40 |
| Behind-Seat Rack | Driver/passenger seat backs | Low | Narrow but high-use | $15–$30 |
| Luton/Overhead Shelf | Above cab, overhead spaces | None | Large but awkward | Free |
| Wall Rails/MOLLE | Any reinforced wall | Moderate | Modular, expandable | $30–$100 |
| Under-Bed Drawers | Beneath bed platform | Moderate | Largest single gain | $50–$200 |
The Discipline That Makes It Work
Finding space is one thing. Keeping it usable is another.
Purge first. Take everything out. Lay it on the ground. If you haven’t used it in a year, it doesn’t belong .
Use clear containers with labels. You see what’s inside without opening. This prevents mystery boxes and wasted searches .
Give everything a home. Items without a designated place become clutter. Every object needs a specific spot .
Secure everything before driving. Non-slip matting on shelves. Latches on cabinets. Locking slides on drawers. Heavy items stored low and centered .
FAQ
Where is the most overlooked storage space in a motorhome?
Behind interior walls and panels. The cavity between the paneling and exterior skin often has several inches of unused depth .
Can I cut into my motorhome walls to create storage?
Only if you reinforce the opening properly. The wall may be structural. One Airstream owner created a platform screwed to the floor inside the compartment before adding a box and slides .
What’s the best way to use a luton or overhead shelf?
Packing cubes or small boxes work well because they keep items together and can be removed easily. Some owners use boxes that double as bed extenders when parked .
How do I organize deep closets in an RV?
Build lightweight shelving inside the closet. If the shelves won’t fit through the door, assemble them in place. This multiplies usable height in a space that only had hanging room .
What are the best collapsible items for a small motorhome?
Bowls, measuring cups, colanders, laundry baskets, and a folding kettle. These take almost no space when stored .
How do I stop things from rattling in hidden storage?
Non-slip matting on shelves. Precisely fitting boxes. Small padding between items. Latching systems on doors .
What’s the “2-inch trick” for van storage?
Recessing panels into wall cavities between structural ribs. It gained four inches of total space in one van build, making a horizontal bed possible .
Final Thoughts
The space you’re looking for isn’t in a catalog. It’s in the walls. Behind the panels. Under the bed. Between the ribs. In the gap you’ve walked past a hundred times without seeing.
Finding it takes curiosity, a willingness to cut and rebuild, and the discipline to keep it organized once you’ve claimed it. But the payoff is real. Four more inches for the bed. A pull-out tray where a solid wall used to be. A shelf in a closet that only held hanging clothes.
Look at your motorhome differently. The space is already there.
