A one-piece composite panel
Walls, roof, and floor are structural insulated panels — a rigid foam core bonded between composite skins into a single piece. No wood to rot, no framing to telegraph cold, no cavities to trap water.
Flatbed campers
Composite flatbed campers for pickups and expedition trucks — the same insulated, no-wood construction as our van bodies, in a camper you can lift off. Order it as a pre-cut kit and build it yourself, or have us build and finish it for you.
The flatbed camper
A flatbed camper mounts to a flatbed and lifts off on its jacks — the truck goes back to work during the week, and you camp on the weekend. You get a four-season composite camper built from the same structural insulated panels, PIR foam, and thermal-break extrusions we put in every Foundation body — light enough to stay within payload, tough enough for washboard roads, and warm enough to camp year-round.

The flatbed
A bed-off flatbed camper gives you the big cabover space and the expedition-truck stance without the cost, weight, and upkeep of a purpose-built monster. It bolts to a flatbed and lifts off on detachable jacks, so the truck goes back to work during the week and you camp on the weekend. Most builds come together in a weekend.
Flatbed configurations
Flatbed campers are built to your truck — single-rear-wheel or dually, with a rectangular or departure-angle rear. Estimated weights are shown below; final numbers depend on options.
| Configuration | Bed size | Camper width | Cabover length | Est. weight |
|---|---|---|---|---|
| Single-wheel · rectangular | 5–6.5 ft (medium) | 75" | 52" | ≈ 808 lb |
| Single-wheel · departure angle | 5–6.5 ft (medium) | 75" | 52" | ≈ 856 lb |
| Single-wheel · rectangular | 8 ft (long) | 88" | 60" | ≈ 968 lb |
| Single-wheel · departure angle | 8 ft (long) | 88" | 60" | ≈ 1,018 lb |
| Dually · rectangular | 8 ft (long) | 94" | 60" | ≈ 1,005 lb |
| Dually · departure angle | 8 ft (long) | 94" | 60" | ≈ 1,057 lb |

Why it holds up
These campers aren’t a lighter, cheaper product line — they’re the same closed-cell PIR foam, one-piece composite panels, and thermal-break AL+PVC extrusions that go into our van and truck bodies. That’s why they stay dry, hold temperature in every season, and shrug off the trail.
Walls, roof, and floor are structural insulated panels — a rigid foam core bonded between composite skins into a single piece. No wood to rot, no framing to telegraph cold, no cavities to trap water.
The core is closed-cell PIR foam: more R-value per inch than the foams in a typical camper, no water absorption, and a wide service-temperature range — a continuous R-11 in the 1.5-inch panel.
Every corner is joined by a hybrid aluminum-and-PVC extrusion that breaks the thermal bridge — less condensation inside the wall, a higher real-world R-value, and a stronger joint.
Two ways to get one
Your kit ships pre-cut with the panels, thermal-break extrusions, corner caps, brackets, hardware, and adhesive, plus a bill of materials and assembly instructions. Most flatbed builds go together in a weekend in a standard garage.
Prefer to skip the build? We’ll assemble and finish the camper for you and get it fitted to your truck — professional assembly is available on every model.
Need more truck?
For the heaviest expedition builds — F-550, Ram 5500, and up — we build a full expedition cabover with high-R, Azdel-reinforced panels on a torsion-reducing subframe, in 15, 17, and 19-foot sizes. That one we build and install for you.
