The rear kitchen layout puts the action at the back of the rig, where a peninsula with bar seating for three, solid surface countertops, and a stainless steel package make cooking feel less like camping. A dedicated laundry room and walk-in closet are the kind of details that matter when you're living in it full-time, and the east/west King bed keeps the bedroom feeling like an actual bedroom. The front bath includes a dual vanity and one-piece fiberglass shower, while a living area desk adds genuine work-from-the-road functionality. Four slides open things up considerably, and with dual 15k BTU air conditioners plus prep for a third, staying comfortable in hot climates is well thought out.
