Stepping into this Supreme Aire feels more like walking into a compact luxury apartment than a motorhome. The front living area centers around the jack-knife sofa, giving you a relaxed spot to stretch out, watch TV, or convert into extra sleeping space when friends or family tag along. The kitchen is set up for real cooking, anchored by the residential Whirlpool refrigerator that actually holds full-size groceries so longer trips don’t feel like an endless run of gas-station snacks.

The bath and a half layout does a lot of heavy lifting: the half bath is perfectly placed off the living area for quick access, while the private rear bath lets you shower and get ready without interruption. In the bedroom, the king bed makes it feel like a true suite instead of just a place to crash, and the wardrobe flip-up bunk adds flexible sleeping or storage space that can adapt to kids, guests, or extra gear as your plans change. Altogether, it’s a floorplan that quietly makes everyday travel smoother, with smarter zones for relaxing, cleaning up, and stashing everything you need.

 

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.

What Our Customers Are Saying

Went above and beyond!

Randy and Tim helped us out. We needed some new batteries on our trip from Indianapolis to Bend, OR. Not only did they get us the batteries, when we needed a new connection made they drove us down to the local Napa and got us back. Also stayed open an hour past closing to make sure we were good. - Dan
