The M1101 and M1102 Cargo trailers are designed to be fully compatible with and towed behind the military High Mobility Multi-Purpose Wheeled Vehicle, (HMMWV). Both trailers have similar width, ground clearance and wheel track as the HMMWV.
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.
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.
