Sorry to hear it Jim, a week after your incident a tow driver dropped our BC onto the bed of his truck. Part was he wasn't fully lined up, second part is I noticed the latch was in the unlock position. We aren't sure how much damage it took yet, shop is full until the 20th then it goes in to get fixed.
Sounds like we might install a Bed saver though after seeing ours drop and reading other posts, it probably will take me half an hour at least to make sure the hitch is locked tight regardless of the receiver and a bed saver. It was just horrific to watch and the worst sound when he pulled out tearing the hitch cap and electrical box.
The surprise to me was not seeing any damage in the bedroom anywhere though one of the fins on the ceiling fan broke off from the jolt, thankfully our insurance is covering all the damage.
