Newmar is a company built around the Christian faith, specifically the beginning of the Mennonite faith in 1525 under the guidance of Ulrich Zwingli, and the founding of the Amish fellowship under Jacob Amman in 1693.


At Newmar, we believe that a motor coach is more than just a vehicle, it’s a passport to countless hours of fun and a lifelong memories taken from quality time spent with family and friends.


For over 50 years, we’ve applied our principles to the creation of motor coaches that have allowed people all over the world to live the RV lifestyle. And we’ll continue to so for countless generations to come. It’s why we take pride in every rivet, weld, and mechanical function.
