Dynamax Logo

From the day the Dynamax brand originated, a progressive vision has set these prestigious vehicles apart. Built to perform at a higher standard of excellence that goes beyond what meets the eye, Dynamax is driven by an unending pursuit for precision and quality inside out and in-between.

Over the years, legendary product integrity and customer loyalty have combined to build a powerful brand. The foundation for success has been simple. Start with a solidly engineered OEM cab chassis platform and concentrate on building a cohesively engineered muscle car style coach on it. The resulting product is visually appealing and structurally solid, with enhancements that improve maneuverability and ride comfort.

We work hard to provide the most enjoyable ownership experience in the industry. Through our dedicated on-site service department and our industry-leading Two-Year Coach Warranty, we are able to provide incredible value and successfully cultivate wonderful relationships with our owners.

At Dynamax, reaching a higher standard is not an option, it’s a tradition. When you take our higher standards of safety, quality, and reliability and then back them up with our industry-leading warranty & customer service, you get a very powerful combination. Just as in a home, an RV provides a number of opportunities for something to go wrong. While we work hard to assure that things do not go wrong, we make sure that our Warranty and Customer Service Support is there to take care of you if something does!

Dynamax is stronger than ever as part of Forest River, Inc. You can have confidence that we will be around to make your ownership worry free for a long time to come.
