It all started with a van…
We started as custom woodworkers, carpenters and engineers with a passion for the outdoors. With a focus on quality work, competitive prices and efficient timelines, we aim to provide the best experience both during the build out of your dream van and while you adventure in your rig for years to come.
After building vans for the past ten years, we’ve expanded to include a rental fleet (the perfect opportunity to try before you buy) and have launched Rossmönster Overland, our truck camper line of expedition vehicles.

Today, we’re proud to offer fully custom and semi-custom van builds, as well as a line of Overland Truck Campers.
If you’re not sure what type of rig is the best fit for you, our rental fleet offers both van and truck camper models so that you can figure out what feels ‘just right’ for you and your adventure crew. And, if you love it , we’ll put two nights of your rental towards your build price when you commit to building with us.
