Following WW II, with the introduction of the 24 volt M-series military vehicles, a new trailer was needed for the M38 and M38A1 jeeps. The M-100 1/4 ton trailer was standardized, a trailer that is very similar to the MB-T (Willys) and T3 (Bantam) 1/4 ton trailers (G529) for the WW II Willys MB and Ford GPW jeeps.
TM 9-2330-201-14 Operator's and Maintenance manual for the M100 and related M115 and M367 trailers. This manual supersedes TM 9-871A (27 July 1951), ORD 7 and 8 SNL G-747 (July 1956) and ORD 9 SNL G-747 (7 February 1952).
There were many small differences between the MB-T/T3 1/4 ton trailers as compared to the M-100 1/4-Ton, 2-Wheel trailer. Visually, the MBT or T3 trailers could be distinguished from the M-100 trailer by these external clues:
MB-T or T3 has a straight brake handle with knob end while the M100 has a curved hook end brake handle
M100 has a grab handle at each corner of the body while the MBT / T3 has no such handles
The trailer is watertight and will float with its 1/4 ton (500 pound) load. A canvas paulin (tarp), which fastens to hooks welded to the body, is provided to cover the trailer top. Two drain valves are provided, one in the front, and one in the rear of the trailer body floor.
A standard M-series intervehicular cable is provided for connecting the trailer tail light wiring with the towing vehicle. The box mounted on the left of the front panel of early M-100 trailers was for the storage of the cable. The box was eliminated in later production.
The M-100 trailer weighs 565 pounds empty. The tarp adds another ten pounds. The inside of the trailer body is 72 inches long by 38 inches wide at the bottom. The FSN of the M100 trailer is 2330-732-8227. Manuals include TM 9-871A and Lubrication Order LO 9-871A.
