The M-104 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 M104 and M104A1 trailers were equipped with 11:00x20 tires to match the M34 and M135 2 1/2 ton 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 M104 was for off-road performance. On highway, the M104 trailer would carry up to 5,500 pounds. The construction of the M104 trailers allowed it to be completly submerged when fording. It was equipped with mechanical overrun brakes and a mechanical hand brake.

The M104 trailers are based on the M102 Chassis, Trailer. The M104 and M104A1 trailers were constructed from welded steel plates, cross-members and wheel wells. Uniquely, the M104 had a tailgate in front as well as at the rear. The M104A1 did not have the front gate but did have a heavier suspension. There was also an M104A2 variant with no front or tail gate.
The manuals for the M104 cargo trailer are TM 9-875B (October 1951), TM 9-8226 (April 1955) and ORD 7-8 SNL G-754 (1954). These manuals cover all the 1 1/2 ton two wheel trailers of the time. The manuals were replaced by TM 9-2330-213-14&P but the replacement manual did not include the then obsolete M102 and M104.
