In Idaho we can only be 75' long. My CC, LB, with a 38' toyhauler and a jet ski behind it is 74'and you cant see what's going on behind the toyhauler which is a little unnerving (needs a camera). This must be 85' long at least. That is a lot of trailering.

Also two ball hitches NOT OK in many states.
Legal length would get him in trouble first.
The two ball or pintle hitch would be assumption or hope on one. I doubt would be an issue. As Semi trucks have the same connection to the trailer/truck in front as the truck to 5W trailer does....I could be wrong on this too.
Here in Wisconsin, the first tow has to be a 5th wheel, not a 5th wheel connected to the tow vehicle by a dolly. Wisconsin also has a max length but ours is only 65'.
