A Structural Interior System, Not a Panel Kit
Most ProMaster interior kits are a stack of raw, unfinished panels with no mounting holes drilled. Building the structure that holds a bed, a galley, or a loaded upper cabinet is left entirely to you.
Inertia solves this with a complete, integrated system that covers the walls and ceiling as one engineered assembly: a machined steel skeleton indexed to the ProMaster's factory chassis points, rot-proof furring and Formica-laminated panels, and GoCode trim to finish the complex curved sections of the van.
Where we are: The first build has been installed and is in the field. The production version is being installed in our show van this month, and will be ready for commercial production in August.
A Continuous Steel Plane, Not Swiss-Cheese Sheet Metal
Van bodies are thin, curved, and full of holes, and the solid metal is rarely where you need a fastener. Inertia gives you a continuous steel plane instead — a cabinet, bed, or galley mounts exactly where the design calls for it, into engineered hardpoints rather than wherever the van happens to have metal.
Inertia provides the engineered structural foundation, and your build mounts to it.
“It doesn't feel like a cargo van anymore — clean, finished, and more headroom than we expected.”
