hitch and pin gap?

[boubou]

quick question. We have a superglide hitch and love it. This is our first 5th wheel (Eagle HT 23,5) and hitch so we don't know any different.
Our neighbours got a used Prowler 5th wheel and seen him drive away with it today for the first time. He stopped on the road, backed up (while hitched up) and the truck moved first, a bang then the 5th wheel started moving too. Then, he went forward and again, the truck moved first, caught the hitch and moved forward. It looks as if there is a gap between the hitch and the pin. and also, an awful screetch when both truck and 5th wheel started to move (temporarily on both forward and backward manoeuvre) Is that normal for a hitch to do this?

I have a Superglide just like you. Our hitch has an adjustment.

What model does your neighbor have?

I don't know, I actually didn't see this, my better half did and explained it to me. I would have gone out and look/see! not that there is anything I could do but he drove off like that!

could it be that his manual slider was left engaged? could he drive like this? how does that work?
I think there gone on a trip?
