Never settle.

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 in is core to Spartan Motors. That’s why Newmar has partnered with us to raise the bar on safety on their coaches.

The Newmar Dutch Star is available on a 40’ or 43’ Spartan K2 450 chassis. Designed, engineered, and made in America with the finest components creating a premier foundation for the most discerning RV makers and owners.

Spartan 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 K2 450 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 chassis are built with care to stay on the road for a good long time.
