The 415G is built around that 15-foot garage, which pairs with a rear patio setup that makes it genuinely functional whether you're unloading dirt bikes or just enjoying the view. Up front, the bedroom sits away from the noise with an optional King bed, while the bath-and-a-half layout means the garage crew isn't fighting over the main bathroom. The kitchen peninsula and residential countertops give the living space a surprisingly homey feel for a unit this rugged. Grand Design backs it all with a MORryde CRE3000 suspension, H-rated tires and axles, and an insulation package that handles real weather. Not just mild weekends.
