That Cummins ISB 6.7L diesel pumping out 360 HP and 800 ft-lb of torque is the headline here. Owners consistently say it "rides like a dream" and handles heavy towing without breaking a sweat, backed by an Allison 3000 MH transmission and a 12,000-lb rear hitch. Three slides open up a genuinely home-like interior with 84-inch ceilings, vinyl plank flooring, and raised-panel hardwood cabinetry, while the overhead cab bunk (rated to 750 lbs) adds real sleeping capacity without crowding the living space. For boondockers, the package is surprisingly capable: four 6V AGM house batteries, a 190W solar panel, an 8,000-watt Onan quiet diesel generator with auto-start, and a 100-gallon fuel tank mean you can stay off-grid without much compromise. The exterior entertainment center, in-motion satellite dish, and Thetford macerator system round out a build that's clearly designed for long-haul, self-sufficient travel.
