Foretravel has crafted exceptional motorcoaches since 1967, using technological innovation. Foretravel is the industry trendsetter and finest producer of luxury motorhomes in the world. No other company can compare to Foretravel’s finish, ride and handling.

You’ve worked hard and earned the ability to explore new places and meet new people on your time. We’re here to make sure your journey is safe, smooth, and always first class. The Foretravel Realm is built exclusively on the Spartan RV Chassis K4 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 RV Chassis makes the only chassis built exclusively for motorhomes. We didn’t take the easy route and modify a truck chassis for our partners at Foretravel. We knew they wanted an unmatched ride and uncompromising durability that was as smooth and quiet as it was safe and well-appointed. So, we built them the unique K4 605 chassis from the ground up. The highest-quality materials provide reliability and dependability, and constant innovation means you’re safe & secure. Spartan RV Chassis provides a comfortable customer experience, nationwide service, and the best warranty in the business.
