Putting the kitchen up front is a bold move that pays off. You get genuine separation between the living and sleeping spaces, and that 8'4" wide-body construction means the front kitchen actually has room to breathe, with solid surface countertops, a deep dual-bowl stainless sink, and a legless dinette that seats four without feeling cramped. The rear bath holds its own too, with a walk-in shower and what owners rave about as colossal under-bath storage. Back in the main living area, the Thomas Payne theater seating comes loaded with heat, LED lighting, and USB charging, anchored by a 40" electric fireplace, and the 6'10" slide height keeps the whole space from ever feeling like a trailer. The one-touch 6-point hydraulic leveling, heated enclosed underbelly, and 200 cu. ft. of heated basement storage round out a package that's clearly engineered for people who camp hard and often.
