SAFETY WARNING FOR TOADS

I'd like to see a picture of the actual hitch that is being used; the drop specifically. I'd also like to see the same from the previous owner. It's quite possible that the previous owner, since they only towed a small trailer, was using a significant drop hitch; class A's typically have a fairly high rear bumper/hitch receiver, requiring a drop hitch, especially for a small trailer. That may have been in place and the PO backed into something (could have even occurred without the PO even knowing). The leverage that rgatijnet talked about can easily put much more force on that area than the actual weight. In any case, the damage has obviously been there awhile (the rust), although it may have just recently "opened up" so that the current owner noticed.
