The Truck
Winnebago Industries unveiled the ARKA, its first purpose-built overland adventure truck, at Overland Expo West on May 15, 2026 in Flagstaff, Arizona. The ARKA is built on a modified Ram 5500 4x4 Crew Cab chassis with a BuckStop super single conversion, 41-inch mud-terrain tires, and a 6.7-liter Cummins Turbo Diesel engine producing 360 horsepower and 800 lb-ft of torque through an eight-speed automatic transmission.
The truck features a zero-torsion four-point pillow-block mounting system that allows the camper box and cab to move independently over rough terrain. A one-piece molded fiberglass roof resists vibration and weather exposure. Exterior upgrades include a winch-ready front bumper, branch guards, off-road driving lights, and on-board air compressor with integrated winterization.
Power & Off-Grid Capability
The ARKA packs 16.8 kWh of lithium battery capacity (two 165Ah Lithionics 51V batteries) with an auxiliary 6500W alternator for on-the-go charging. Four 200W solar panels (expandable to 1,200W) provide renewable energy, supporting up to 14 days of off-grid operation in temperatures from -10ºF to 120ºF. Towing capacity is rated at 15,000 pounds.
The 20Z floorplan sleeps four and includes a full kitchen, wet bath, and dinette. Winnebago's Connect system provides off-road driving information display and system monitoring.
Expo Debut
The ARKA made its public debut at Overland Expo West on May 15-17, alongside over 400 exhibitors. Winnebago is now accepting pre-orders for the 2027 model year ARKA 20Z at a starting price of $331,901. Deliveries have not yet been announced.
