Winnebago Goes Full Expedition Vehicle

Winnebago is best known for traditional RVs, but the new ARKA Adventure Truck pushes the brand into far more serious territory. Built on a Ram 5500 chassis and heavily upgraded for real backcountry use, this is less motorhome and more expedition vehicle with a comfortable cabin attached.

Underneath sits a 6.7 liter Cummins diesel paired with a BuckStop conversion, 41 inch tires, single rear wheel setup, onboard air, and a 15,000 pound towing capacity. The ARKA is clearly designed for people hauling boats, motorcycles, recovery gear, or anything else that turns remote travel into an actual expedition rather than a weekend campground trip.

The living module is where things get more interesting. A molded one piece fiberglass shell combines with serious insulation, hydronic heating, heated floors, and heated tanks to create a true four season setup capable of operating from minus 10 to 120 degrees. Unlike many overland builds that still feel improvised, the ARKA feels engineered as a complete system from the start.

Inside, the layout stays modular and practical. The rear section transforms between seating, sleeping, and a full height heated gear garage depending on how the truck is being used. Aluminum cabinetry, L track mounting points, and durable materials keep it functional rather than overly polished, while still delivering enough comfort to live out of for extended periods.

Its off grid capability is equally serious. Up to 14 days of autonomy comes from a 48 volt electrical architecture with lithium batteries, expandable solar, fast alternator charging, heated water tanks, and integrated filtration. This is a rig designed to stay out, not constantly search for hookups or campsites.

Winnebago Connect also avoids feeling gimmicky. Real time pitch and roll monitoring, climate control, tank management, freeze protection, and optional Starlink integration actually make sense in a vehicle designed to operate far from infrastructure.

At over $330,000 fully equipped, the ARKA sits directly in EarthRoamer territory, and that feels intentional. Winnebago is no longer just building RVs for highways and campgrounds. The ARKA is the clearest sign yet that the brand wants a place in the modern expedition vehicle world.
