Shell Structure: Made using a composite sandwich system. The outer and inner skins consist of fiberglass-reinforced polymer (FRP) panels with a high-density expanded polystyrene (EPS) foam core, creating a lightweight, rigid, and thermally efficient shell

Walls, Roof, Floor: All panels—walls, roof, and floor—are this composite sandwich. There is no wood framing anywhere. Floors use a composite fiberboard (not plywood), which offers high strength at minimal weight.

Our 2" wall panel system offers ~R10 insulation

Havn

$299,485.00

The Rossmönster Havn was created to solve a common challenge: more interior space without the extreme off-road build of the Baja series. Designed for those chasing adventure on dirt roads and trailheads in spacious luxury.

Offered through our dealer network, the Havn is built to be repeatable, which means faster delivery times and stronger resale value than a fully custom van. It’s a new kind of Rossmönster build—designed for versatility, backed by craftsmanship, and ready for wherever the road leads.
