M101 Trailer, Cargo, 3/4 ton.

The M-101 Trailer, Cargo, 3/4 ton is a single axle, two wheel, steel frame cargo trailer designed to be towed by a 3/4 ton or larger truck. A welded steel box body is bolted to the frame. The body is equipped with a tailgate and mounting brackets for cargo racks and a frame for a tarpaulin cover. A steel A-frame is bolted to the frame with an attached one-position lunette, landing gear, and two hand brake levers. The M101 is designed to operate on all types of roads, cross-country terrain, and in all weather conditions. There are no restrictions on the M101 for movement over primary and secondary roads, however, it is restricted to a maximum speed of 15 mph when towed cross-country.

The M101 Trailer, Cargo, 3/4 ton, was manufactured in the 1950s and 1960s as the trailer for the M37 3/4 ton cargo truck. Multiple manufacturers produced the trailer under a series of contracts. The M101 remained in use for decades as a general cargo trailer towed by any of the commonly used military vehicles rated for 3/4 tons or more.

The M101A2 wheel lug pattern matched the M880 truck and had tubeless tires. The M101A3 one ton trailer was towed by the HMMWV when the HMMWV was introduced in the mid-1980s. To improve performance and simplify logistics, the M101A3 trailer included modifications such as a longer axle and increased ground clearance, and was fitted with HMMWV wheels and runflat tires.

Trailer, Chassis, 3/4-ton, M116A2/M116A3.  The M116A2 and M116A3 trailers are single axle, 2-wheeled, general-purpose chassis designed to be towed by the HMMWV. They are constructed to transport electric power generators but can be configured to haul items such as motorcycles and satellite dishes by adding different beds to the chassis. The M116A3 has a wider bed and provides an increased payload over the M116A2. The M116A3 utilizes the HMMWV radial run flat wheel and tire assemblies. The M116A3 consists of a steel A-frame draw bar bolted to the frame with an attached one-position lunette, landing gear and two hand brake levers. It is designed to operate on primary and secondary roads at a maximum speed of 50-mph and cross-country at a maximum speed of 30-mph. The M116A3 with cargo body makes up an M101A3 trailer.

The lifted trailer appears to have a 1/4-ton trailer in its bed.
