Each kit is a CNC-cut subfloor in three panels sized to the ProMaster’s floor, with mounting adhesive included. Top flooring and its adhesive are sold separately. The kit is available on its own or alongside the Structural Interior System, and Transit and Sprinter floors are coming soon.

Two Tiers

Marine-Grade Plywood, $1,795

• The plywood tier uses panels rated for marine use, with waterproof adhesive and void-free cores, in the same three-panel layout.

Coosa Bluewater, $1,995

• Coosa Bluewater is a structural fiberglass composite rated about 30% lighter than marine-grade plywood, and it won’t absorb water, swell, or rot.

For the top layer, we can point you to precision-cut vinyl flooring through our material partner. Inertia products are currently sold through Overland Mobile Installs and Camper Van HQ.
