2026 Leisure Travel Vans Unity TB4X Storm Grey

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.

Storage without compromise.

As the first Leisure Travel Van to offer both a dedicated pass-through gear garage and up to 5,000 pounds of towing capacity, the Unity TBX provides space for your gear and the ability to bring more along for the journey—empowering you to explore more with comfort and capability to spare.

Adventure-ready.

Bringing a fresh, adventure-focused look to the Unity lineup with options such as a Black Accent Package, black wheels, and all-terrain tires, the TBX offers a balanced blend of rugged and refined design.

TB4X Exclusives

Exclusive to the Unity TB4X are matte-black rear fender flares and a factory Mercedes-Benz lift, adding further capability and giving the Unity a more assertive, confident stance.
