The rear living layout keeps the bedroom tucked away at the front for real privacy, anchored by a King bed, walk-in closet, and thoughtful touches like elevated CPAP shelves, USB and 110V outlets bedside, and adjustable reading lights. The kitchen island gives you actual prep and gathering space, and the 5,000 BTU decorative fireplace makes the living area feel genuinely cozy rather than just functional. Full-timers consistently praise this floor plan for its carry capacity and livability. One owner reports no regrets after a year on the road, and the stackable washer/dryer prep, central vacuum, and Four Season Living Package with in-floor heating ducts back that up. SolarFlex 200 comes standard, with upgrade paths all the way to the 1200i-L for serious off-grid capability.
