The 3700BH-OK is built around a layout that keeps adults and kids in their own corners, a King bed in the rear master, a separate front bedroom with a loft above it, and a bunk room in between with its own half bath. The outdoor kitchen with metal slam-latch doors and LED motion lighting makes it easy to keep the party outside, while the farmhouse sink, kitchen island with flip-up counter extension, and solid surface countertops give the interior a kitchen that actually functions. East to West leans heavily into the extended-season angle here: Azdel laminated sidewalls, a 60,000 BTU tankless water heater, heated and enclosed underbelly, 12V heat pads on the tanks, and a 48" electric fireplace mean this rig isn't just a summer camper. The universal docking station consolidates outside shower, waste flush, dry-camping water fill, and winterization into one tidy panel, a genuinely useful touch that shows some thoughtful design.
