For what it is worth, I have pulled a lot of trailers, including trailer houses. It is not probable that the hitch came unlatched from a bump, or "slipped over" the ball, with the facts you have given. Someone playing a cute trick, or you forgetting to latch the hitch is far more probable. I have a couple of times, found at destination to my horror, that I had forgotten to latch the coupler when I hooked up. The advantage of putting a lock or bolt thru that hole, is that you HAVE to latch it to get that to happen.
I have seen people drop the coupler on the ball, with the latch portion then pushed up in the coupler, and then latch it thinking they were connected, when in fact they were just laying on top of the ball.

Getting a lot of good info. Thanks. The ball fits tight and There is no adjustment. Looked a couple time. We are thinking the trailer was empty, rear tire one side went down, front going up, slowing down all at the same time just put to much shove foreword and up at the same time making the hitch come open. I think I will be locking it down with a bolt or a lock from now on.
