    engine has 80k, truck/trans has 150k. body is pretty beat up so it has been worked, would it be worth it if i can get it for 6k, how long can i expect a trouble free life out of the allison?

    its an 01 with a 9ft dump, dump is very solid, frame is just starting to lose factory undercoat.

    I just need a few years out of it for the bigger work that is beating up my 01 2500hd

    it is also 4x4

    Those 8.1 have great power, and I think the Alison is the best transmission you can get in any truck.

    6 thousand seems like a very fair price, I'd pay it for that truck, put a plow on it and make all the money you spent on it and more in the first winter.

    That's a steal. I would buy it. The Allison behind a gasser should go forever. 8.1's get terrible MPG's, especially working, but that's a $10k truck IMO. I do wonder though why they had to do a motor at 70k......doesn't seem right.

    they did the motor because the shop broke the ear of the engine when doing the starter. since they were covering removing/installing an engine he found one for cheap with 80k, and figured it was a good time to put one in. the cab corners rusted through and were poorly fixed and rusting again, but now have bedliner on them too. the fenders are rusted to crap and dented up, rust all along the top of windsheild, interior is what you would expect from a 150k work truck (well worn). I have decided to pass on it, i can afford to buy it, but wont have money to put on a plow or money to cover repairs that may pop up, i am just gonna put the money into my current truck and jeep, then look into another dump in the spring since i will primarily need this for summer work. not sure what i will have for commercial plowing yet this year

    8.1's were a 200K mile service engine according to GM. I wouldnt worry about the trans if it shifts fine. They can take some abuse and are hard to limp in a stock 8.1L. Just smell the fluid in it. Im not easy on mine by any means and running a hot tune even when towing and have not had one problem other than little stupid maintenance stuff. Id buy it if it drove right. We cant tell how it drives so thats on you ;)

    I had a 8.1/Allison in a 2500HD I had before I started landscaping/plowing. It was a great truck the motors are really strong as are the trannys. I dont think you'd have to worry about the the drivetrain at all. The rest of the truck is what you make of it. If its gonna be a work truck, then whats the point of finding a gem? its just gonna get beat up anyway. When I had my 8.1 I was getting pretty good mileage, much better than my truck I have now with the 6.0

    Glad I saw this. I had a pretty much done deal with the guy a couple weeks ago, I was getting ready to drive 4 hours. He never called me the day he wanted me to come get it. Glad I didn't now lol
