You’ve earned the right to explore new places and meet new people. We’re here to make sure your journey is safe, smooth, and always first class. As the industry leader in chassis-centric innovations, improving the safety culture is core to Spartan RV Chassis. That’s why Newmar has partnered with us to raise the bar on safety on their coaches.
The Newmar Mountain Aire is available on a 40’ or 45’ Spartan K3 500 chassis. Designed, engineered, and made in America with the finest components creating a premier foundation for the most discerning RV makers and owners.
Spartan RV makes the only chassis built exclusively for motorhomes. We didn’t take the easy route and modify a truck chassis for our partners at Newmar. We knew they wanted an unmatched ride that was as smooth and quiet as it was invigorating and well-appointed. So, we built them the unique K3 500 chassis from the ground up. The highest-quality materials provide reliability and dependability, along with nationwide service, and the best warranty in the business.
Motorhomes riding on a Spartan RV chassis are built with care to stay on the road for a good long time.
