On the power front, you get 400 watts of factory-installed solar, 350 amp-hours of battery storage, a 2000-watt inverter for household AC power. 15,000 BTU of air conditioning handles warm-weather comfort, and 25,000 BTU of furnace output tackles chilly evenings. The kitchen features a Single-door compressor refrigerator for keeping provisions cold. The 12.5-foot awning creates a shaded outdoor area that becomes a favorite gathering spot at camp.
Power comes from a Mercedes-Benz 3.0L V6 Turbo Diesel, paired with the proven Mercedes-Benz Sprinter 3500 platform, delivering 188 hp. A 35-gallon fuel capacity running on Diesel gives you confidence on cross-country drives.
The $259,000 price tag reflects the no-compromise approach Thor takes with this flagship model, using premium materials and craftsmanship throughout.
