DIFFERENCES BETWEEN MODELS.
NOTE
•
Light HMMWVs that have been modified have a decal on the rear crossmember where the pin-
tle attaches that states: “AUTHORIZED TO TOW TRAILER WITH MAX GROSS WEIGHT
OF 3400 LBS”. An MWO tag should also be present on the driver’s side reinforcement panel
(just behind the seat) that identifies MWO 9-2320-280-20-7 has been applied.
•
Heavy HMMWVs that have been modified have a stencil on the rear bumper reinforcement
plate that states: “AUTHORIZED TO TOW TRAILER WITH MAX GROSS WEIGHT OF
4200 LBS.” An MWO tag should also be present on the driver’s side reinforcement panel (just
behind the seat) that identifies MWO 9-2320-280-20-6 has been applied.
a.
The difference between the M1101 and M1102 cargo trailers is listed on the Identification and Shipping Plates.
The difference between the maximum Gross Vehicle Weight (GVW) is based solely on the towing vehicle. All
trailer models can be towed by a HMMWV M1097/M1114 series in accordance with the identification plate.
The M1101 cargo trailer and the trailer chassis can be towed by a HMMWV M998/M1038 series when the
GVW does not exceed 3400 pounds. To determine which HMMWV can tow a chassis version of the HMT,
look at the trailer data plate that identifies the total system weight. Use a modified light HMMWV if system
weight is 3400 lbs or less. Use a modified heavy HMMWV if system weight is 3400-4200 lbs. There are no
physical differences between the M1101 and M1102 trailers. Refer to table below for towing vehicle require-
ments.
b.
The data listed on the Trailer Chassis Identification and Shipping Plates is different from both the M1101 and
M1102 trailers. In addition, the trailer chassis has no cargo body.
