and M813A1 cargo trucks have 7 x 14-foot (2.14 x 4.27 meters) flatbed boxes. The M814
cargo truck has a 7 x 20-foot (2.14 x 6.1 meters) cargo box. The M813A1 truck has
hinged dropsides with 147-1/2-inch (372.51 centimeters) access openings on both sides. A

b. Purpose of the Vehicles. The M813, M813A1, and M814 cargo trucks are used to
transport equipment, materials. and/or personnel. The M813 and M814 cargo trucks
have permanent steel-welded sides. For this reason, they are preferred vehicles for use in
transporting bulky payloads that may shift during transit. The M813A1 cargo truck has
hinged steel sides that can be folded down and out of the way of loading and unloading
operations. The M813 and M813A1 vehicles provide 550 cubic feet (15.4 cubic meters) of
cargo space, and the M814 vehicle, which is 72 inches (183 centimeters) longer, provides
744 cubic feet (20.8 cubic meters) of cargo space. Some M814 vehicles are equipped with
front winch. This feature makes it more versatile for operations under difficult field
conditions.

that require easy side access to cargo. An example of this is a ground-to-truck forklift
operation. The M813A1 dropside cargo truck is preferred for this operation. The M814
cargo truck is not suited for operations requiring maneuverability in limited spaces
because of its longer cargo body.
