Built with Grand Design’s commitment to quality, the 21G includes a fully enclosed underbelly, rugged chassis construction, solar prep, fuel station, power awning with LED lighting, and pass-through storage. Its manageable size makes it easier to tow and maneuver while still offering the capability and features expected from a premium toy hauler.
