The rear living layout is the real draw here. Instead of a back bedroom, you get a proper living space with a fireplace, ceiling fan, and a rear window that opens up the room. The kitchen punches above its weight with a farmhouse sink and island, and the booth dinette tucks in neatly without eating up the whole space. Up front, the bedroom features an east/west bed (upgradeable to a Platinum Series King bed), dual vanity, and a bathroom you can actually access even with the slides in. Washer/dryer prep, dual-heated holding tanks, and a 76-gallon fresh tank make it a solid choice for longer stretches away from hookups.
