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. Entegra Coach and Spartan

Motors, your co-pilots on the adventure of a lifetime.

Entegra’s Cornerstone is built on the 45’ Spartan K3 605 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 K3 605 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.

Safety Innovations

Spartan Advanced Protection System – Cornerstone

Spartan Advanced Protection System® is the industry’s first and only comprehensive safety system engineered to keep your Entegra Cornerstone coach on the road, and safe… to enjoy every adventure.

  • Collision Mitigation with Adaptive Cruise Control alerts the driver of potentially dangerous driving scenarios and adjusts speed to maintain a safe following distance.
  • Electronic Stability Control (ESC) helps the driver maintain control of the coach in extreme steering manuevers by automatically controlling individual brakes to help keep the coach moving in intended direction.
  • Spartan Safe Haul™ The industry’s only factory-chassis integrated air supply for tow vehicle brake systems.
  • Automatic Traction Control (ATC) helps the driver maintain traction under the drive axle tires in slippery conditions by automatically applying brakes on the wheel end that is slipping. This helps transfer power to the wheel end with more traction.
  • Tire Pressure Monitoring System (TPMS) displays tire pressure and temperature for  individual tires. The system will alert the driver if any tire pressure or temperature exceeds set thresholds. The system is expandable to monitor towed vehicles as well.
