The Horton Model 603 is designed for the customer who needs it all -- maximum payload, rugged durability, and extra large storage and work areas. The Model 603 utilizes the popular medium duty chassis and features a 166" body and 68" headroom and is even available with a walk-through option. Full rear suspension is standard on the Ford, Navistar, Freightliner or GM chassis and provides excellent ride characteristics as well as a "kneeling" loading position.
