The Newmar Difference

We love RVs. And we build them for people who love the RV lifestyle. That's why for over 40 years, the Newmar mission has been to create recreational vehicles that are unlike any others.   

We hold ourselves to a higher standard of craftsmanship. We infuse a deeper level of pride into our work. We continually push ourselves to innovate and lead. That's what makes Newmar different.

Impeccable RV beauty, durability, comfort and affordability. Those are just a few of the qualities that create the Newmar difference.

The Newmar Mission

Newmar was created by RV people…for RV people. As a company, we were founded under a singular, distinct vision: to make the best RVs possible. That’s because our founders, Marvin Newcomer and Marvin Miller, knew how much well-made, functional, innovative recreational vehicles mean to the people who own them. They were RV enthusiasts themselves…and had experienced firsthand the passion and enthusiasm which a great RV can create.

The Newmar Community

Newmar makes a commitment to every owner. That's why we're a world leader in making incomparable luxury coaches that offer comfort, durability, quality, and reliability. Get involved in the Newmar community. We have a lot to offer. Kountry Klub, an exclusive social club for Newmar owners, was formed in 1985 and quickly grew to be one of the leading social clubs in the entire recreational vehicle industry.
