    for about 4 weeks i have been driving and alley docking with a 2 axle truck. now that truck has a transmission problem so now i have to move to a 3 axle truck. i didnt really have a big problem docking with the 2 axle ill get it in 8/10 tries but now im struggling to dock this truck with the 3 axle im lucky to get it in 3-4/10 tries. So is there a big difference backing between the two?

    Slight difference.

    The bigger difference comes when you go from a daycab to a tandem axle sleeper, or a stretch frame.

    Are you asking about a tridem trailer, opposed to a tandem?
    Or the tractor going from single drive to two drives?

    Single drive to two drives.

    Gotcha. If the wheelbase is the same, there won't be much difference. There's a bit more to it though. Each brand of truck has a different wheelcut, as well as each model.
    I'm assumming it's the same make/model, so usually the wheelbase will be a bit longer, and it will take the tractor a little longer to turn, especially in reverse. You'll get used to it.
    The truck I usually drive is a 4900SA day cab, turns great, forward or reverse. Then I get the other truck, T800 with sleeper, world of difference there. But after an hour or so, all is good.

    I think you've already answered your own question.:biggrin_25525:

    the wheel nut just needs slight recalibration :) wait til they give you a 53 foot trailer and teeny tiny yard to dock it in, or a set of "B-trains"
