The front kitchen layout is the 421FK's signature move. You get a full-size French door refrigerator with ice maker, Fisher & Paykel dishwasher, four-burner range with convection microwave, Calcutta solid surface countertops, and a kitchen island with bar seating that would look at home in a real house. The rear King bed suite adds a dual vanity, 40" smart TV, and a dedicated desk slide, so there's a genuine separation between living and sleeping spaces. Residential touches run deep: Truma on-demand hot water, Splendide stackable washer/dryer, 5,200 BTU fireplace, hardwood dovetail drawers with soft-close everything, and two 15,000 BTU heat pump A/Cs keeping both ends comfortable. The automatic 6-point hydraulic leveling and LCI Road Armour suspension make setup and towing far less of a production than you'd expect from a rig this well-appointed.
