## Overview

Owners consistently describe the Newmar Mountain Aire 4589 as a luxury diesel pusher that's built solid and drives beautifully, which is a big part of why so many people run it as a full-time or extended-travel coach. Newmar's Mountain Aire line sits at the top tier of the Class A world, right alongside the Dutch Star and Ventana, and this 45-footer delivers that reputation with a comfortable, well-appointed interior that sleeps six. It's the kind of coach people talk about as the best they've owned.
