Bath and a half, rear bath, front living, dual vanity
The Keystone Alpine 3700FL puts the living room up front where the views are, anchored by a 40" electric fireplace and Thomas Payne theater seating with built-in heat, LED lighting, and USB charging. The rear is devoted to a King bed suite with dual vanities, a full bath, and washer/dryer prep, while the half bath up front means nobody has to trek to the back mid-day. A kitchen island, solid surface countertops, residential fridge, and a legless dinette with storage round out a layout that feels genuinely livable rather than just spacious on paper. The 200 cubic feet of heated basement storage, one-touch six-point hydraulic leveling, and enclosed Nautilus water works center show that Keystone leaned hard into convenience features on this one.
