M1085 Long Wheel Base (LWB) Truck

The M1085 Long Wheel Base (LWB) Truck is designed to transport soldiers and cargo in International Standardized Operations Containers . The M1085 has a payload capacity of 10,000 pounds and to facilitate loading/unloading, the bed side rails are mounted on hinges. The cargo bed can be equipped with an optional bench seat kit for transport of soldiers. The bench seats are constructed of a non-wood material and attach to the cargo bed side rails. The seats can be folded down and stowed when not in use. Soldiers are assisted climbing in and out of the cargo bed area with the aid of a ladder stowed on the vehicle when not in use. A canvas and bows kit is provided to keep soldiers and cargo protected from the elements. The M1085 can be equipped with a self-recovery winch capable of fore/aft vehicle recovery operations. The winch has 280 feet of line capacity and 15,500 pounds bare drum line pull at 110% overload.
