The Jeep trailer was a small 1/4-ton cargo trailer designed to be towed by U.S. Army Jeeps. There are several examples of the M100 on display at Estrella Warbird Museum.
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.
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.
