Built on a Super C chassis, the Newmar Supreme Aire 4573 pairs the muscle of a heavy-duty diesel platform with the kind of upscale finish work Newmar is known for. Owners consistently point to its comfort, abundant storage, and solid, well-built feel, and at 45 feet it sleeps six without giving up living space. This is very much a top-tier coach, with a single full bath and the luxury appointments you'd expect from Newmar's flagship end of the lineup.
Other class c motorhomes floor plans (around 44 ft 11 in, near $633,000), similar in size and price to the Supreme Aire 4573.
