The separate 13-foot garage is the star here. Owners consistently call it the sweet spot for fitting ATVs, dirt bikes, or gear without sacrificing a livable front section. Two entry doors mean you're not crawling through the living space every time you need something from the garage, and the bath and a half layout keeps the morning routine from turning into a bottleneck. Grand Design loaded the exterior with thoughtful touches: a 30-gallon onboard fuel station with interior and exterior gauges, Rockford Fosgate speakers with a powered sub, and motion-sensor storage lighting that actually makes late-night unpacking bearable. Construction-wise, the laminated aluminum framing and R-40 roof insulation punch well above the toy hauler average for this size class.
