Same here - I lock it at storage and if it's parked at home and unhitched when I'm getting ready.
Never locked it while camping. I have 4 slides, an awning and water/electric/sewer normally. Someone would have to really want it to go through the effort of disconnecting to steal my camper. And, if they do... I have insurance for that.
