    The converter dolly gets its name because it is a dolly that converts a semi trailer into a full trailer. Full trailers are perfectly legal to tow behind a truck, provided the hitch is rated for the weight.

    Had a strong pintle on my dump, it was only good for 13000 max. And that was off the plate from the builder next to the hook.

    Im pretty sure we loaded it a touch more than that some days. Just dont need a ambulance chasing lawyer to see it and add up the trailer weight. Or a couple of other towing situations we have been involved in where a bar was attached to the steer axle of the towed vehicle. (With me in it as mr brake, not my idea of a good driving experience.)

    I for one would not be doing that trailering to a dolly to a pintle. It's just aint done.

    I am thinking that the rating is a vertical load not a pulling load.

    The hook on the back of LTL trucks are just for moving a dolly by its self .

    i'll get into exactly why i brought up the original question in a sec, but first i want to make clear and establish that there doesn't seem to be that much, if any, tongue weight on the pintle (and thus no weight on the truck or trailer that the dolly is hooked to? ), or is there?

    One time, i unhooked the lead trailer from the dolly, but left the dolly latched under the rear trailer-----just to see if it could be done. There didn't seem to be too much weight on the actual pintle (circle part); Yes, i could re-hook the lead trailer without too much trouble. Granted i was not loaded very heavy in the rear trailer.

    I wouldn't trust it even pulling. On our tractors the latch is relatively flimsy. And the eye hook is loose when hooked up to it. So you get a lot of movement. With the weight of a trailer with all the slack and yanking would probably break it.
    Especially loaded. An empty pup MIGHT be possible. But I still wouldn't trust it.

    For the purposes of this discussion, let's assume that the pintle hook on the tractor IS rated to tow a converter dolly with trailer attached----equivalent to the pintle hook on the back of a trailer.

    Then, as I stated, it is perfectly legal.
