disconnect, hide electrical cord when overnite at Walmart?

I don't unhook anything. As far as putting locks on all the tow bar pieces, I use a couple but not enough to keep me from unhooking the toad in an emergency without keys.

Had a that had a lock everywhere there was a hole to the point that he couldn't separate the toad from the coach. Toad caught fire and he wound up with two piles of ashes, one for the toad and the other for the coach.
