disconnect, hide electrical cord when overnite at Walmart?

there as you put it people who will steal any thing, even their grandmothers teeth., just for the fun of it. I have heard so many times that people come out of the store from doing their shopping and someone pulled the handle on their 5th wheel hitch and the unit falls on the sides of the truck. just good ol' boys having fun. it's a shame, there are stupid people like this out there.
