    12000 miles on my allison/duramax one ton. Getting 13 mpg working around town with an average payload of 1200 lbs, 17 mpg highway. The 6 speed shifts as smooth as silk, the engine is very quiet, interior very comfortable. Think twice about GM before you go ford or dodge!

    I agree. I have 12,500 on mine. My city is around 11, but thats because theres a stop sign at every block, and i rarely go over 30 mph. My highway is around 21. I towed 3.5 pallets of 80 pound bags of concrete mix, and this thing really hauled a$$.

    I agree. Second thoughts for a while with fuel cost but in the long run -towing, etc this trucks rolls. I have an 08 d-max - 4 door GMC. Leather etc. To nice for work but well work it. I also opted to get the tool box on the rail system thru GM - really not impressed yet on that.

    Definetily think twice if considering a ford or dodge. To me there is no comparison!

    I have been averiging just over 16 around town/mixed and just returned from a trip to NY thru PA & VA mountains and averaged just over 18, with a best of 19.7 (always fill to top of fill neck so it is accurate) only 6700 miles.

    Thought about GM, went and looked at them; naahhhh!

    I'm happy with my Ford. Still bought American though. :usflag:

    Don't much care for that Japanese-Isuzu Diesel engine parked under the hood of GM trucks. However, I do like that Allison transmission.

    But it's still Japanese. You just said so yourself.
    Of course, I think it is great that the Japanese have created such a great engine, but if I am going to purchase an American made truck, then it had better be American through and through; not one with parts manufactured in Mexico with diesel engines designed by the Japanese. If I wanted a Japanese engine, then I would just go back to a Toyota.

    I personally saw where Ford manufactures (most of) their wiring harnesses for their trucks...along a mud packed street in a VERY dillapidated town in Mexico, donkeys wondering around, women carrying the laundry to the creek on their heads, cows and pigs struttin their stuff and all of a sudden out of nowhere a blue oval on the wall. The local guys that were entertaining us told us the wiring harness for FMC are manufactured RIGHT THERE! I know its alot of work to rewire your ford truck though so just keep running it till it lets you sit.
