The vocational Model 389 is ideal for applications such as dump and logging and available in a low-profile configuration to meet the needs of the car carrier industry. Lightweight components, like the all-aluminum cab and the industry’s only aluminum hood, as well as a variety of lightweight front and rear suspensions, allow for increased load capacity. The ProBilt® interior is specifically designed for vocational applications and features five grab handles and a dash made of durable materials that are easy to clean and shows fewer scratches and scuffs.
