    AI summary

    The rear-living layout is the real draw here. You get a proper living space at the back of the coach anchored by Thomas Payne furniture, an L-shaped sectional, and a 5.5K BTU electric fireplace with remote control, all in a 100" wide-body frame that actually feels like a room. The hidden pantry tucked behind the entertainment center is a clever touch, and the kitchen holds its own with solid surface countertops, a deep single-basin stainless sink, and pendant lights over the island. Outside, Keystone loaded this one up practically: heated and enclosed underbelly, one-touch 4-point leveling with hookup memory, heated pass-through storage, and an outside shower with hot and cold. The optional washer/dryer and freestanding dinette with ottoman are worth a look if you're planning extended trips.
