The rear-living layout is the headline here. It puts the main living area at the back of the trailer where the slide-room windows let in the most light, while the bedroom stays up front with its own louvered tread steps and a pillowtop Denver mattress. Cabinetry is built with hand-rubbed maple doors, solid hardwood drawer fronts, and full-extension ball-bearing drawer glides, which is the kind of detail that holds up after years of road miles. Outside, the walk-on roof decking, factory ladder, outside shower, and speakers make it genuinely usable beyond the four walls. The insulation package. R-30 floor, R-40 residential wood-framed roof, and the one-piece TPO roof with a 12-year warranty back up Grand Design's reputation for putting quality where it counts.
