What we manufacture
A Foundation composite camper body is an insulated, one-piece composite shell — the structural habitat we manufacture and install on a van, cutaway, or truck chassis. It arrives square, sealed, and build-ready, so you or your builder can finish the interior without framing out a cargo van or a wood box. The same body is used for four-season adventure campers, expedition rigs, and commercial and specialty vehicles.
At a glance
One body, many chassis
The body is the product; the chassis is the platform underneath it. We build it in standard sizes and install it on the chassis that fits how you drive and what you carry.
How it works
Do-it-yourself camper builders who want a finished, insulated shell to outfit; overland and adventure buyers who want a four-season habitat; commercial and specialty operators who need a clean, build-ready mobile workspace; and professional builders and manufacturers who build a repeatable product on a consistent body.
We manufacture the composite body and install it on your chassis as a final-stage manufacturer — the structural shell, insulation, subframe, cab-over, passthrough, and the doors, windows, and hatches you specify. The interior — cabinetry, electrical, plumbing, HVAC, and furnishings — is done by you or your professional builder. We supply the platform; you or your builder complete the fit-out.
Ford Transit and Mercedes-Benz Sprinter cutaways, the 4x4 Ford E-Series (E-350/E-450), and medium- and heavy-duty trucks — Ford F-450/550, Ram 5500, Chevrolet 4500–6500, and military-grade LMTV/FMTV. If you already run a chassis, we can usually build on it.
The body is a one-piece composite structural insulated panel: a rigid foam core bonded between composite skins. It carries load on its own, so it is light, square, and stiff. It is fire-retardant, with no wood to rot, absorb water, or grow mold, and no stud frame to telegraph cold through the wall.
Every body has a continuous R11 insulation layer with no thermal-bridging framework cutting through it, so it holds temperature far better than a bare metal van — warmer in the cold and cooler in the heat. The core is closed-cell PIR foam, which delivers more R-value per inch and absorbs very little water.
The walls are flat and truly square, with integrated mounting built into the panel. Cabinets, benches, and equipment go straight in against a solid, 90° surface — you are not shimming a curved cargo-van wall or framing out a fiberglass shell before the real build can start.
A truck or van frame twists over rough ground. We install the body on a torsion-reducing subframe that pivots between the two, letting the chassis articulate over the terrain while the subframe absorbs the twist — so far less of it is transferred into the composite body and the body stays square. That is what guards against cracked walls, sprung doors, and leaks over time.
Either. Because the body leaves our shop road-legal and titled, you can outfit it yourself or take it to any professional builder or upfitter. Our preferred builders can finish the whole interior — electrical, cabinetry, and everything inside.
Yes — that is our builder program. Outfitters and manufacturers build on our standardized composite body as a repeatable starting point and keep their interior, brand, and customer, with private-label options and support from prototype to production.
A cargo van curves in at the roof and walls, has no real insulation, and has to be furred out before anything goes in. A Foundation body starts square, sealed, and insulated, with true standing room and full-width space — so the usable interior is larger and the build goes in faster.
