Where rugged meets refined.

Introducing the all-new Unity TBX—blending the strength of the Mercedes-Benz Sprinter with adventure-ready upgrades and flexible living spaces—setting a new stage for modern RV adventure without compromise.

Innovative living spaces.

The Unity TBX reimagines RV living with a floorplan centered on versatility, comfort, and smart use of space. Featuring two distinct living areas, the TBX offers an open living and dining space up front and twin beds in the rear. It accommodates seating and sleeping for up to four, with all four travel seats forward-facing and equipped with shoulder belts.
