In 1968, Marvin Miller and Marvin Newcomer left their jobs at an RV manufacturer and founded the Newmar Corporation in Nappanee, Indiana. Their goal? Build coaches that were better than anything else on the road.

Newmar began by building high-quality travel trailers. In 1971, the company introduced the Kountry Aire fifth wheel, making Newmar one of the first and largest fifth wheel builders in the industry.

Newmar continued to grow at a rapid pace through the 1970s. In 1984, Mahlon Miller, who at the time was president of the Holiday Rambler Corporation, left his position and purchased a 51% stake in the Newmar Corporation.

In the 1980s, Newmar entered the Class A market, building premium-quality motor coaches in small numbers. In 1990, the company introduced two iconic motor coaches that still exist today: Dutch Star and Mountain Aire. At the same time, Newmar began pioneering concepts and features that would change the industry, including the first traditional slideouts and flush floor slideouts ever featured in a Class A coach.

In 1991, Mahlon Miller purchased the remaining 49% of Newmar Corporation, becoming sole owner. Just one year later, the company built a new, 116,000 square foot, state-of-the-art manufacturing facility in Nappanee, helping to further centralize production.

By the late 1990s, Newmar became the first to offer full body paint on both its towable and motor coach products. To support the growth of this innovative practice and ensure superior quality, Newmar added a 45,000 square foot paint facility. Then, in 2004, a 150,000 square foot chassis prep and welding facility was added to accommodate the growing complexities that come with manufacturing top-quality motor coaches.

In 2006, Mahlon Miller’s son Matt became Newmar’s new president. When the economic recession arrived soon thereafter, Matt Miller insisted Newmar stay the course by maintaining its commitments to dealers and customers. In 2012, Newmar exited the fifth wheel segment that helped shape the company decades earlier, choosing to focus entirely on crafting the finest Class A motorhomes the industry had ever seen.

Today, Newmar is stronger than ever thanks to an unwavering commitment to service, quality and innovation that remains unmatched.
