    Hello and thanks,

    I have a new 2018 Tractor three axle 244" wheelbase setup. I am being offered quite a few loads to western Canada. I would like to run 7 axles total. I live in Utah. I would like to learn about Jo Dog / Single axle jeep setups. I know they are not legal in California. Where are they legal? Where are they not Legal? Details please not guessing. LOL. Do states where they are legal give you 20k for the Jo Dog? What are the drawbacks? Doubles on my license i know. Over length issues? Do you have to jump/stack or place on trailer when empty? Who runs this in the states?

    Thanks to all.

    Wow, ok i didn't know it was going to be this difficult. I guess I'll simplify my question. Anyone know where single axle jeeps are not legal.

    again thanks,

    Sorry that the class is not much help. We had a jodog expert from Canada on the board, but he was banished for clubbing a baby seal with a bottle of Labatts, or was it clubbing a snowflake with the truth.....I forget.

    I cannot answer your questions with any certainty, but I do believe that our former resident expert has used his jump jeep in the states.

    It's difficult to give a straight answer to this question because its going to depend on the specific setup that you have. Most states allow single axle jeeps, as to what weight you're given, it's going to depend on your axle spacing. Most single axle jeeps/ jump jeeps aren't long enough to meet the 8-6 spread needed in most states to be considered a separate axle. As such, typically it means your drives will be considered a 3 axle grouping, not a 2-1 grouping.

    So, to answer your question? It depends on what you're getting and where you're going, as things typically go in heavy haul.

    TN will permit you 60K on a 3 axle group, so it should be usable in TN.

    first of all, thank you all. i can see that this is pretty grey and not so black and white. i have even received emails from the jeep manufactures stating "most states" "nearly all" "and you shouldn't have a problem" i appreciate all of this but as you can imagine i can't make a big decision on guesses. can anyone suggest a place for me to turn too. i have even started to look at each state and the data is just not there. california states they are not legal in a glossary of "axles" doesn't say why? just nope. so if you don't mind may i ask a few more questions. what is an axle group? such as how close together? common air? can someone please explain the 8' 6" mentioned above? if the jeep axle was 9 feet from last tractor driver would it be a new axle group? i can add a tag axle to the truck but that will not help in canada. anyway you are all great...

    regarding coloradogreens statement of a 3 axle group versus a 2-1 group. i guess this only pertains to legal loads? 34k + 20k against a 42500k tri? permitted they would both be 60k correct or no?

    It really depends on where you're at. If the jeep had more than an 8-6 spread from center of last drive to center of the jeep axle, in Colorado that would qualify as a 2-1 grouping, which would get you, on a drive grouping, 75,000lbs, vs 70,000lbs on a three axle closed drive grouping (77,000 on a 2-1 trailer grouping, vs 65,000 on a closed tridem trailer grouping).
