WARNING Towing trailers too large or too small for the vehicle capacity is dangerous. These trailers do not track vehicle properly, cargo shifting occurs, and the likelihood of trailer capsizing during movement is increased. This could result in damage to equipment, and injury or death to personnel. CAUTION Be sure to close tailgate before towing trailer. Failure to do so may cause damage to the master cylinder. NOTE • Towing any trailer with a HMMWV other than the authorized M116 series, M101 series, M1101, and M1102 trailers or a M102 howitzer is not authorized. • When towing a trailer, the maximum safe slope is reduced from 40% to 30%. All vehicles are capable of towing M116 Series and M101 Series trailers and the M102 Howitzer. The M998 Series and A1 Series have a maximum towed load capacity of 3,400 lb. The Heavy Variant (M1097, M1097A1, M1097A2 and M1123) and A2 Series have a maximum towed load capacity of 4,200 lb. Only vehicles that have been retrofitted with MWO 9-2320-280-20-6 Airlift Bumper Reinforcement, or MWO 9-2320-280-20-7 Crossmember Reinforcement, are authorized to tow M1101 and M1102 trailers.
