The difference between the M1101 and M1102

So you’ve seen all the military trailers appearing on the streets and in public. You might think there is only one Military Tactical Trailer pulled behind the HMMWV, but there are two trailer that look the same, but have one unique difference between them.

Physically there’s no difference between the trailers. Up close or from a distance they look identical. But if you look closely at the identification plate on the tongue of the military trailers you’ll notice there are two model numbers; the M1101 and M1102. The only difference between them is the axle weight carrying capacity. The M1102 can carry 900 lbs more than the M1101. Here’s the scoop.

The M1102

The M1101 is classified as the Military Light Tactical Trailer LTT-H (heavy) with a maximum gross weight limit or carrying capacity of 4200 lbs. M1102 and M1101 can be towed with heavy HMMWV M1097/M1114

The M1101

The M1101 is classified as the Military Light Tactical Trailer LTT-L (light) with a maximum gross weight limit or carrying capacity of 3400 lbs. M1101 can be towed with light HMMWV M998/M1038.

There is speculation there is really no difference besides a new name plate. Yet, the manufacturers state the bumpers on HMMWV’s were found too weak to tow the trailer at it’s maximum designed weight of 4200Lbs. So a different pintle/mount system came out for the HMMWVs came out, allowing the towing of M1102 units. Light HMMWV’s were limited to tow the M1101, identical to the M1102, but weight limited to 3400Lbs.

Either way, the likelihood of someone carrying more than the stated M1101 capacity of 3400 lbs is pretty slim so the upgraded M1102 isn’t really needed unless you have a large piece of machinery such as a generator or carrying gold bars.
