mine this time got pinched in the jaws of the hitch.....I had noticed it seemed to be hanging low. Guess it was a little too low and I caught it with the hitch backing in this last time. I got the 12" in the mail today and to the naked eye it looks to be the same size as what I have on there now. The first one was put on by the dealership so I have no idea what it was. I'll find out in a couple days when I go out to pick the camper up for our last summer trip of the year. They're only $10 so if I have to get the smaller one I will....not a big deal.
