The 13' garage provides substantial space for ATVs, motorcycles, or other gear, with a Fast Ramp rear ramp door, Ram-Air garage vents, protective diamond plate garage walls, and 2,500-lb. rated flush-mount tie-downs. The garage also includes a half bath and can provide additional living or sleeping flexibility, while the fold-down side patio creates another elevated outdoor space for relaxing and entertaining.

Grand Design's M-Class construction brings thoughtful features for year-round camping, including Weather-Tek insulation, a triple-insulated garage floor, Stealth AC system, 12V tank heaters, and an enclosed and heated underbelly and storage area. A 330W solar panel with 50-amp controller and inverter prep adds off-grid capability, while the MORryde CRE3000 suspension, MORryde pin box, 17.5" Cooper H-rated tires, and 6-point hydraulic leveling system provide a solid foundation for traveling with this large toy hauler.
