About the Newmar Mountain Aire

When one of the founders of Newmar was nearing retirement, he sold his shares of Newmar Corporation to Mahlon Miller, on the condition that the company remained local in Nappanee, Indiana and continued to use the high quality materials and workmanship that are synonymous with Newmar’s brand.

One of the first things Mahlon Miller did upon assuming full ownership was launch Newmar’s first foray into the luxury Class A coach market with the Mountain Aire and Dutch Star in 1990. Both coaches remain popular today as proof that high quality products withstand the test of time.

As one of their flagship Class A coaches, the Newmar Mountain Aire is understated and timeless, featuring fine details and thoughtful design. Available in six unique floor plans, this chalet on wheels is ready to carry you wherever the wind calls.
