At just 14,388 miles and priced nearly $300,000 below its original MSRP of $645,283, this Newmar Mountain Aire 4543 is one of those rare opportunities worth dropping everything for. Newmar's reputation for fit-and-finish is well-earned, and the Mountain Aire sits near the top of their lineup — owners consistently describe these coaches as having the kind of build quality where you're genuinely hard-pressed to find something to complain about.

The 4543 is a diesel pusher, which means serious torque for highway cruising, and the full bath keeps things comfortable for extended trips without compromise. Newmar's construction philosophy emphasizes real-world livability alongside the luxury details — practical storage, premium materials, and a layout that actually functions the way you'd want it to on the road.
