If I were you, the first moment I saw the fellow out around his rig I would have walked over...chatted him up and bring up the fact that his rear jacks are being strained hard due to the way he unhitched. Just because his helpers were drunk, or he goofed up I would want to at least offer a warning to the potential damage. I have done the same thing trying to level my 5er only to remember my back jacks were put down by a well meaning helper. just my .02
No helpers doing this. He did this by himself and saw it several times over the weekend.
He had very little problem getting it in the site, despite the "helpers", so probably not a newb.
I have often found that advice should not be given unless asked for.
I didn't need to cause problems for both of us for the remainder of the weekend.
It's his rig, he can do what he wants.
I wonder why his electric jack was locked up, when we were dumping, on our way out?
