I know this is a late reply and not consistent with the other posts , but - We once left our camper for a short time with the propane on as was normal for us. When we returned, a neighbor thankfully had shut off my propane after a squirrel had gnawed thru the exposed hose and propane was blasting thru the campground. I now turn off propane, and water, when I leave for more than a few minutes, just to be safe. Only takes a minute.
