The garage is the centerpiece here, a euro-style setup with a manual garage bed, canvas wall at the ramp door, and a 30-gallon fuel cell with its own pumping station, so you're not scrambling for fuel on trail days. Back inside, the kitchen punches above its class with a 12V French door black refrigerator, convection microwave, 3-burner cooktop, and a 60K BTU tankless on-demand water heater that actually keeps up with a full group. Two 15K ducted ACs handle the load in warm weather, and the 30" fireplace makes shoulder-season camping genuinely comfortable. The "X" Package adds an LED smart TV and fiberglass front cap, while 200 watts of solar and a docking station give you a solid foundation for off-grid stretches, with generator prep and an optional inverter if you want to go further.
