A new nose and grill are the latest in a series of significant walk-in changes introduced by Workhorse Custom Chassis, a manufacturer of chassis for walk-in trucks, motor homes and buses.Workhorse is a wholly owned subsidiary of International Truck and Engine Corporation, and the grill of the new nose design makes the Workhorse walk-in a clear cousin of International’s models.The initial Workhorse model is now available on an 86-inch wide body. Within the next couple months, a 96-inch wide body will be offered. Both models have cargo body lengths from 10 to 22 feet, built on the full range of Workhorse gas and diesel chassis options from 9,400 lb. GVWR to 23,500 lb. GVWR. Workhorse uses General Motors 4.8, 6.0 and 8.1L Vortec gas engines and International’s 4.5L MaxxForce 5 V6 diesel powerplant.
