TM 9-2320-387-10
2-27. TRAILER TOWING
.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.
M1113 and M1114 vehicles are not authorized to tow M1101 or
M1102 trailers unless they have been retrofitted with
MWO 9-2320-280-20-6; Airlift Bumper Reinforcement. Towing these
trailers without the airlift bumper reinforcement MWO applied
could result in damage to equipment or 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%.
The M1113, M1114, M1151, and M1152 vehicles are capable of towing a M116 Series,
M101 Series, M1101, or M1102 trailers and the M102 howitzer. M1113, M1114,
M1151, and M1152 vehicles have a maximum towed load capacity of 4,200 lb (1,907
kg) as specified in table 2-3.1.
Trailer payloads should be evenly distributed to prevent excessive tongue loads.
