Four slideouts in a nearly 45-foot coach give the Newmar Mountain Aire 4586 a living space that genuinely rivals a high-end apartment. Newmar sits in the upper tier of Class A builders alongside names like Dutch Star and Ventana, and the Mountain Aire line reflects that reputation with thoughtful livability details rather than just raw size. The single full bath keeps the layout focused, channeling the square footage into generous living and sleeping areas for up to six. Worth knowing: as of 2024, the Mountain Aire 4586 was no longer being offered as a new floor plan, making pre-owned examples the path in.
Other class a motorhomes floor plans (around 44 ft 10 in, near $817,000), similar in size and price to the Mountain Aire 4586.
