The Aria Class A diesel motorhomes by Thor Motor Coach offer handcrafted interiors, fully equipped kitchens, the latest technology, and powerful engines providing everything you need and more!


Each is hand-built on a Freightliner XC-R raised rail chassis and up-fitted with the Atlas Foundation. These models include Air-Ride suspension and Sachs shock absorbers for a smooth ride, and with an l-beam front axle that has a 55-degree wheel cut, you may never want to stop driving. Each Aria has a unique layout to meet your lifestyle, and it includes dual roof air conditioners, a tankless water heater, LED lighting to illuminate the polished porcelain tile flooring and Studio Collection cabinetry, window solar and privacy roller shades, and so much more that comes standard.
