This floorplan is all about giving you a true residential flow from front to back. At the rear, the rear bath feels like a private retreat, with the kind of space and privacy that makes getting ready feel un-rushed, even on travel days. Just ahead, the bedroom features a dresser with optional washer and dryer below, so you can keep clothes, linens, and laundry all in one organized zone instead of living out of bags and campground facilities. In the heart of the coach, the galley kitchen is set up for real cooking, not just reheating, with generous overhead cabinets that actually hold dishes, pantry items, and small appliances instead of forcing you to stash things all over the coach. Up front, the jack-knife sofa pulls double duty as a daytime lounging spot and an easy extra sleeping space at night, rounding out a layout that quietly makes longer trips feel simple, comfortable, and put-together.

 

The Newmar Supreme Aire Super C diesel motorhomes continue to raise the bar with even more luxury and innovation you will not find on most other Super C coaches. Built on the Freightliner Cascadia chassis with serious diesel power and heavy-duty towing capability, they are made for confident travel whether your destination is the coast, the mountains, or anywhere in between. Inside, the Supreme Aire feels more like a high-end residence than a motorhome, with refined cabinetry, premium seating options, and a thoughtfully designed living area that can be tailored to how you relax. A sky window above the cockpit brings in natural light when you want it, and the power shade lets you dial it back for movie nights or mid-day naps. Up front, air-ride captain’s chairs, a modern digital dash, and the Xite infotainment system work together to make every mile feel smooth, quiet, and under control.
