The M-105 1 1/2 ton 2-Wheel Cargo Trailer (G-754) was developed in tandem with the M-series of cargo trucks that were fielded in the 1950s to replace the World War II vintage vehicles. The M105 trailers were equipped with 9:00x20 tires to match the 2 1/2 ton truck and other cargo trucks. With the same tires, the combination truck and trailer would ride at the same height.
The ton and a half cargo rating of the M105 was for off-road performance. On highway, the M105 trailer would carry up to 5,500 pounds. The construction of the M105 trailers allowed it to be completely submerged when fording. It was equipped with air over hydraulic brakes and a mechanical hand brake.
