The 15-foot garage is the headline here. Large enough to haul serious toys and convert into a second sleeping space when you're parked for the weekend. Grand Design built the 381MS around the idea that you shouldn't have to choose between roughing it and living well, so you get a spacious kitchen and upscale interior alongside the hauling capability. Owners consistently call it the highest quality coach on the market, and with sleeping for seven across the main cabin and garage, it handles a full crew without feeling cramped. This is a rig that earns its place at the trailhead and at the resort.
