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 Ventana is available on a 40’ or 43’ Spartan K2 400 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 400 chassis. With Spartan’s Advanced Protection System, true automotive-grade comprehensive collision mitigation, electronic stability control, adaptive cruise control, and integrated tow-vehicle braking are now available to Newmar customers.

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.
