The beginner’s guide covers the decisions: shell or tent, what to measure, and the safety rules. This guide covers the build: how to lay out a platform, choose a mattress, and organize storage so the setup works trip after trip — and so the truck still works as a truck on Monday.
Start with the layout, not the shopping list
A truck bed camping setup has four jobs: sleep, shelter, store, and cook. The bed itself is the bedroom and the garage; cooking happens outside it. Sketch the layout before buying anything, because the bed is small and every inch is spoken for:
- Sleep zone: the flat platform and mattress, full length of the bed.
- Storage zone: under the platform, in drawers or bins, plus the space beside the mattress if the bed is wide enough.
- Access zone: the tailgate end, where you climb in, reach bins, and load gear without crawling over the mattress.
- Kitchen zone: outside, downwind of the sleeping area, on a table or tailgate — never inside the shell or tent.
Short beds favor convertible platforms that fold or split so the bed can carry cargo by day. Long beds can host a fixed platform with full-length drawers and a mattress that stays put. Decide which kind of trip you take most, and build for that one; a setup that tries to do everything does nothing well.
Building the platform
The classic DIY platform is a sheet of 3/4-inch plywood on a 2x4 frame, built level with the top of the wheel wells. That height — usually around 9 to 11 inches above the bed floor — is what turns the bed into a flat rectangle roughly 48 inches wide even in a mid-size truck, and it leaves 12 to 18 inches of storage height underneath.
Build it in three steps:
- Measure and cut. Measure length, width at the wheel wells, and wheel well height at three points, and cut to the narrowest measurement. Cut the plywood to fit between the wheel wells, with a center spine and cross braces underneath for support. Seal the edges against moisture.
- Make it removable in sections. A single full-size sheet is hard to get in and out alone. Two or three sections, or a bi-fold design, let one person install and remove the platform, and let you fold half of it away for tall cargo.
- Finish the surface. Wrap the plywood in marine-grade outdoor carpet. It prevents splinters, cuts down road noise, and keeps the mattress from sliding around while you drive.
Pre-built options exist for people who would rather buy than build: sliding drawer systems sit under a raised deck and give you weatherproof drawers that pull out from the tailgate. They cost far more than plywood and add significant weight, so check the manufacturer’s official site for the weight, the load rating, and whether the system fits your exact bed before ordering. A lighter middle ground is a set of low-profile bins under a simple platform — no drawers, but everything is still sorted and reachable.
Add tie-downs. L-track or simple D-rings let you strap bins down so they do not migrate across the bed on rough roads. Loose gear in a truck bed is a noise problem on a smooth road and a damage problem on a rough one.
Choosing the mattress
Three options cover almost everyone:
- Foam mattress on the platform. A 4-inch high-density or memory foam pad, often a tri-fold, is the most common choice among regular truck campers. It needs no inflation, it insulates, and it folds away. Cut it to the platform shape or buy a truck-specific size — and measure first, because a mattress that is an inch too wide will curl up at the edges and ruin the flat surface you just built.
- Foam mattress on the bed floor. Cheaper and simpler: a foam pad straight on the floor, no platform. You lose the under-bed storage and the flat surface over the wheel wells, so it suits short trips and occasional use.
- Inflatable truck bed mattress. Shaped to fit around the wheel wells, it packs to the size of a sleeping bag when deflated. It is the best option if the truck must stay empty for work during the week — but it offers no insulation, it can deflate as the night cools, and it needs a foam pad underneath in cold weather.
Whatever you choose, layer insulation under it: interlocking EVA foam tiles or a closed-cell foam pad between the mattress and the platform stops cold from radiating up into your back. Several experienced guides describe this as the single biggest comfort difference, and it costs less than almost anything else in the setup.
For bedding, use a sleeping bag or a duvet and warm blankets rather than cotton quilts, which hold dampness. Keep a dedicated dry bag for the sleep kit and do not open it until the sleeping area is set up and dry.
Storage: bins, drawers, or both
The goal is simple: everything has one assigned home, and you can reach it without emptying the truck. A practical system is three zones under and beside the platform:
- Sleep and shelter bin: sleeping bag, pad, pillow, and the bed tent or tarp, kept together so setup starts with one bin.
- Kitchen bin: stove, fuel, cookware, and utensils — fuel stored exactly as its label and your transport rules require, never loose in a general tote.
- Tools and recovery: jumper cables, tire inflator, basic tool roll, headlamps, and first aid, in a bag that stays in the truck between trips.
Clear, stackable totes with latching lids work well under a platform, and labels on the ends — not just the tops — let you read them when they are slid under the bed. If you build drawers, make them full-extension so the back half is reachable, and size them around the bins you already own rather than buying new bins to fit the drawers.
Keep heavy items low and over the axle, light bulky items high, and anything you need at night — water, light, warm layer — within reach of the sleeping position. The test of a good layout is a rainy night: can you get water, find your headlamp, and reach the door without getting out of the sleeping bag and without opening three bins?
Weather protection, power, and light
A camper shell is the set-and-forget answer for weather: mount it once, and the bed is dry every trip. A truck bed tent takes 10 to 20 minutes to pitch and gives you standing headroom at the tailgate, but it needs its rainfly taut and its straps checked in wind. For either one, a tailgate seal kit blocks the rain, dust, and insects that sneak in at the gaps.
For power, a portable power station or a second battery earns its place only after you know what you actually run overnight — usually phones, lights, and a fan. Start with a USB power bank and a 12-volt outlet, and size up only when the bank runs dry twice. LED strip lights or a lantern on a hook beat a flashlight rolling around the bed, and a small fan makes a hot night in a shell bearable.
Ventilation matters in a shell more than in a tent, because the space is smaller and tighter. Crack a vent or a window on the lee side, and keep a small gap even on cold nights: your breath adds moisture all night, and a sealed shell wakes up wet inside. If you run any fuel-burning device, a carbon monoxide detector inside the sleeping space is not optional.
Packing order: load once, in the right order
Pack in reverse order of need. First in, last out: the platform sections, then the storage bins, then the mattress, then the sleep kit on top. The kitchen bin and the water container go in last or ride in the cab, so they are the first things out at camp. Keep the setup checklist taped inside the tailgate or in the glovebox — after the third trip, you will know it by heart, but the list catches the one item you forgot when you were in a hurry.
A setup that takes 45 to 90 minutes the first time should take 15 to 25 minutes once you know it. If it still takes an hour on trip five, something in the layout is fighting you: usually a platform section that is too heavy to move alone, bins that only come out in one order, or a mattress that has to be wrestled into place. Fix that one thing before the next trip, and the setup gets faster every time.
