Alan,
Those are really classic.
It grieves me to say I have seen even worse. Back in the 80's when on a boilermaker field job in Nevada, one of our new hands pulled in with a 5th wheel unit mounted to the roof of his station wagon. There was hardly any added reinforcing done to strengthen the roof mount area. And he was proud of it.
Lord, just keep me off the road when these guys are anywhere in the vicinity.
Have a Great Day, Brent
