after doin some reading it seams that m35s can legally pull 10000lbs but can handle way more, but the m105a2 are only rated at 1 1/2 tons so my question is what else did they tow while inservice and where can i get something bigger?
For one thing, they would tow a broken down deuce if necessary. Wreckers were not always available in a war zone, or might have already been in use. Yeah, the spec says 10K pounds, but in the military, that means little or nothing. Just a go-by.
On public roads, there is a huge difference. Still, you will see a deuce pull a deuce in an emergency condition, though, it is probably not appropriate if it came under scrutiny.
I've pulled over 10K with a deuce before. It will slow you down, especially on hills that are going up. LOL
Most important thing of all is leveling of the trailer and good brakes on the trailer.
My trailer brakes that were air over hydraulic would stop the deuce before the deuce brakes would stop it, when I wanted them too. As a matter of fact, I had to be careful not to lock up the trailer brakes on a quick stop. You get used to it like driving a different old car. They all have their personalities. It's fun learning and working with them.
The M1061 trailer will hold 10K up top, and it weighs in at about 5K pounds. Some of the best 4 landing legs on a 5 ton 14' trailer you'll ever find. They will lift the entire trailer with 10K up top, and you can change out a tire without a jack. Amazing.
