I had a minor backing accident a few months ago and I have a backup camera. Was backing the motorhome into the shop using the camera and the mirror. I had some cut hardwood lumber stacked up along the wall and was trying to get close to it. The only thing I didn't calculate on was the tail pipe sticks out from the side of the motorhome by a few inches and I was trying to get within a few inches of the lumber. Tailpipe caught the lumber and pushed it over into the fiberglass before I saw what was happening. Just left marks that can be buffed out. And I used to load military vehicles onto airplanes so it can happen to the best of us.
