    1,000 lbs is highly negligible. I think my state has a tolerance of 2,000 lbs. My personal tolerance is around 3,000 lbs. If you are pulling a twin screw, nobody at the scale would even notice that you are running them out of sync.

    Don't sweat 1k. I won't rebuild a 2k difference if I'm not going far, but if I cross a state line anything over 1k gets rebuilt.

    Never know when Johnny DOT decides to have his bad day all over your cdl.

    Also watch that rear if its empty. They can jump around like a fish.
     
    Pullin2 Thanks this.

    I had a 20k front box and 3k back box once,crossed the AZ scales,and my singe drive axle was 1k over,so the DOT told me to go around back and "fix"it..I was thinking "well how do l do this without a sliding 5th wheel" So l rotate my boxes,cross the scale, and he says your legal on all your axles now get out of here,Ok Dont have to tell me twice,Was I legal to have a light box in front of a heavy box? I dont know,but l didnt get a ticket that day..

    And ain't that a fine kettle o' fish?

    And they wonder why we can't take the DOT seriously. Inspecting and weighing for safety my big toe.

    Well all l can report is what happened,not why it happened,maybe he was just being cool that day and didnt want to write a ticket,maybe he was tired and wanted to go home so he didnt give a lecture on the line up of the trls,or maybe they dont care about the weight per trl, just as long as your gross & axle are good, then your good..

    It's probably legal, but incredibly stupid.

    That was one dumb cop. :confused:

    First of all, I assume by "A train" doubles you mean two 28' trailers?

    I don't mean to insult your intelligence, but I've never heard the term before.

    Anyhow, what I do is weigh the set. The best case scenario is for axle weights to read progressively smaller as you go back from the drive axle. The dolly axle scaling more than the front trailer axle is okay as well, so long as the rear trailer axle still scales less then the dolly axle. That just simply tells you that both trailers are nose heavy.

    What IS a problem however, is when the front trailer axle scales less individually than the dolly AND the rear trailer axle. Regardless of what may be printed on any manifest, encountering this scenario when weighing is a dead giveaway that the trailers are backwards. I pretty much swear by this because every time I've switched the trailers after finding this, I would reweigh and find the axle weights reading just the way they're supposed to, smaller from front to back.

    Now, I personally am very meticulous in what I do, and any instance of the scenario described above will result in me switching the trailers, regardless of weight difference. Some guys will not, but pretty much as long as you don't drive like a nut, it is perfectly safe to roll like that.

    A-train, B-train and C-trains.

    A trains, same type of converter most ltl use. B trains, tandem super B's, C train, rear axle slide out like GFS.
