Some one broke into several RVs in the storage facility where mine is stored several years ago. They used a screwdriver (or something) to get in my basement to steal a few things. Bent the tangs on the locks and no damage or even any noticeable marks on the basement doors. They only keep honest people honest.
They did not get inside my 5er. Thought it was because I had latched the deadbolt, until I saw another trailer on one side and a motor home on the other side where they had broken out the door windows and got in.
