That failure looks a lot like mine, but only the damage to the lower hitch head. When mine went it did not bend up into the the upper unit and I suffered no damages to any other part.
I did give some thought about having the bottom plate of the lower unit reinforced but time wasn't on my side as we were heading out on a 3 week trip. I think I may look back into having it done or doing it myself over the winter now that I'm hearing about these other failures.
