Have you seen some of the rigs running up and down the road with rookies behind the wheel!
Yes, we have seen some of the most bone-headed dumb things you can imagine by people driving all types of RVs. Some examples, hitting fuel pumps with trailer tail-swing, backing into things, following too close, driving way too fast, no anti-sway, trailers so out of level front to back that you can't imagine anyone would think it's a good idea, no weight distribution so the tongue weight is so overloading the truck that the headlights are pointing to the sky, cutting us off with their trailer, because they forget they have a trailer, trailer sway accidents, the examples could go on and on.
That said it is crazy what people are allowed to drive with no special license.
I saw a guy who had never driven a truck pulling anything in his entire life, bought a 25k lb 5th wheel. He went into the local dealer and bought a dually truck, hitched it up to the 5th wheel, and drove away. At least he was smart enough to be scared, as he should have been, but he wasn't smart enough to not do it. You could also buy a class 8 based rig or pull a large 5th wheel with a class 8, having never even sat in the driver's seat of a big truck.
In my opinion there should be some licensing required, because lack of experience strongly equates to safety issues. If you don't even have to demonstrate knowledge and driving ability to handle those issues, then how can one be safe?
I'll bet
@OLEJOE has seen so many examples you wouldn't believe it.
