OUR Story

We started as custom woodworkers and engineers, primarily focused on unique home builds and wood products in Colorado. The challenge and excitement that came from building unique adventure vans sparked a desire to break free from the standard mold. Now we build vans to share our knowledge and promote experiencing life on the road. We continually push the boundaries of craftsmanship and functionality in the camper van market.

This Ram Promaster van alongside everything installed in the conversion is brand new. Everything was professionally installed by Rossmönster Design, based out of Boulder, CO.
