As for the goose-neck being idiot proof why are safety chains required in most states?
Probably because a goose-neck hitch uses a ball and the states regulations specify that a ball hitch must use safety chains.
In my opinion, the law makers probably were not thinking of goose-neck hitches when they wrote that law. The goose-neck hitches have very little, if any, chance of coming off of the ball while in use and probably do not need to use them. Even if one did, the tailgate of the truck would probably catch the hitch and keep the trailer from running away.
In addition, the location of the ball in the middle of the bed above the axle rather than 3 or 4 feet behind the axle results in much less bouncing at the ball area. Also, the hitch itself is part of the framework of the truck and not stuck on the back like a normal receiver is with the ball attached to a shank. I have seen normal hitches torn loose but have never seen a goose-neck hitch torn out of a truck.
All of the above, in my opinion, would be reasons that a goose-neck hitch does not need safety chains even though they are required in some states because of faulty regulations.
By the way, bringing the "big guys" into the conversation has no bearing on this discussion. They are two completely different things in my opinion and probably the reasons the "big guys" use normal 5th wheel hitches is because that is the only type of trailer made for commercial, over the road, interstate commerce. I have never seen a goose-neck commercial box trailer. I have seen car haulers and some other types of flatbed trailers but never a "normal" over the road trailer. Hence, they have no bearing on the topic being discussed here.
