Light Tactical Trailer (LTT) M1101 & M1102 Characteristics

The Light Tactical Trailer for general cargo is designated by two model numbers, the M1101 and M1102, depending on its loading by weight. That is, there is no physical difference between the M1101 and the M1102 models, other than the dataplate. The two model numbers are used to regulate the Gross Vehicle Weight (GVW), based solely on the vehicle towing the trailer.

For example, when the GVW does not exceed 3,400 pounds (1542 kg) the M1101 cargo trailer can be towed by a HMMWV M998/M1038 series prime mover. Both the M1101 and the M1102 trailer models can be towed by a HMMWV M1097/M1114 series in accordance with the identification plate. Due to the numerous model differences, for military use operators must refer to TM 9-2330-392-14&P to determine towing authorization for the M1101 and M1102 for the specific set of circumstances.

The Light Tactical Trailer M1101 or M1102 is a single axle, two wheel trailer designed to be towed by a HMMWV towing vehicle. The high ground clearance trailer consists of a cargo box mounted on the Light Tactical Trailer Chassis. The nomenclature and NSNs are:

  • Trailer, Cargo: 2-Wheel, Light M1101 (NSN 2330-01-387-5443)
  • Trailer, Cargo: 2-Wheel, Heavy M1102 (NSN 2330-01-387-5426)

The M1101 and M1102 trailers have the same tires, wheels, and track width as the High Mobility Multipurpose Wheeled Vehicle (HMMWV).

A hand-brake lever and cable assembly located on each side of the trailer activate a service brake at each wheel. Control of each service brake is independent. In addition to handbrake-activated service brakes, the trailers are equipped with an inertia-actuated hydraulic brake system (surge brakes). The trailer suspension consists of one shock absorber on each end of the axle. Two stabilizers, stored in the front and installed in the rear, provide stability during loading or unloading cargo while the trailer is not coupled to a towing vehicle. A rear tail gate drops down to assist loading.

The only difference between the M1101 and the M1102 trailers is the model information and payload capacity stated on the dataplate.
