Never settle.

Why would you settle for anything but the best? We’re here to make sure your journey is safe, smooth, and always first class. Entegra Coach and Spartan Motors, your co-pilots on the adventure of a lifetime.

The Entegra Aspire is available on either a 40′, 42’ or 44’ 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 Entegra. 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.
