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.

Interior & Layout

Welcome to the Great Indoors.

Want to see the Havn on the road?

Follow our YouTube for build stories and trip footage from the Havn, or dig into the back catalog for the engineering problems we have already worked through. Ross, Luke, Theo, and the whole crew, building and testing these things for real.

Systems

Built to go, and to stay.

More Room. Same Footprint.

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. A new kind of Rossmönster build, designed for versatility and ready for wherever the road leads.

Customize Your Own

Every Havn leaves the shop ready for four-season, off-grid travel — super singles, watertight garage, molle panels and storage cabinets are all standard. The options below are what you add on top, and the real configuration conversation happens with a person, not a checkbox.
