I showed this to a die hard Ford truck fan here at work. I expected him to go into his usual rant about how my Chevy is junk, yada yada, but he just looked at me and said, "Yeah, my truck did that too."
He was hauling a front loader on a trailer that was hitched to his receiver instead of his gooseneck hitch. He went across some fairly good sized dips in the road and he said in a split second it bent just like the one in the photo. Didn't take the dealer long to fix and he said he couldn't really tell where it bent the frame anymore. Dealer charged him $500.
