MWO - Modification Work Order.
Yes on that trailer you can clearly see the MWO work right in the picture. There are 3 orders . 2 are actual changes, and 1 order for just an inspection.
And even if it wasnt done, you would never have to worry about it. You will never test the unit to destruction on the Munson Test Course at APG like the Army did. When they ran the tests the trailer was destroying the frame cross members on the humvee where the pintle hook mounted, unlike when the humvee towed the M101 series trailer at lower speeds.
They came out with a MWO for the rear of the humvee that reinforced the frame cross member to allow the humvee to tow the new M1101 trailer. And even then the trailer was too much for the standard humvee. So when the trailer was renamed from HMT High Mobility Trailer, to LTT Light Tactical Trailer, they de-rated the GVW to a lower number and called it the M1101. The M1101 was authorized to be towed by a standard humvee with no rear bumper, just the pintle hook mounted to the frame cross member.
Then they created the M1102 model LTT which was the *exact same trailer* except for the data plate, and authorized it only to be towed by Heavy Hummers such as the HHV M1097A1 and others with the Heavy Duty rear airlift bumper in either the all steel version or the aluminum version with the steel reinforcing plate in the center where the pintle hook goes. The M1102 data plate shows the full Max GTWR.
The brake controller was replaced with a new version designed by TACOM that was more durable but the one that was replaced is still out there on tons of military trailers such as the M101A2, M101A3, M116A1 etc. The shock absorber set up in the old version was not up to running on the sinewave track at the Munson Test Course with the trailer fully loaded to GTWR max, at high speed behind a humvee. It was designed for the lower off road speed that was always spec for trailers until the humvee and HMT/LTT spec came out. So TACOM came up with one with rollers instead of the swing arms and a new shock absorber that was more durable.
You have a fine trailer there at a great price. The only problem with them is they are as wide as a humvee and a lot of people do not like the fact that they do not look right behind a pickup unless it is a dually. Standard 3/4 ton 8 lug wheels with lower profile tires will bring the height more in line with a civvy truck, and changing the light bulbs to 12 volt, along with a new trailer connector to match a civvy truck are common mods.
