Many years ago there was a report of where a gas station employee was changing a filter on a pump, and an RV pulled in. There was an explosion, the employee was killed, and the RV was destroyed.
We've had a couple of mh where the access to the back of refrigerator was not far from the gasoline fill. So I added a switch within reach of the drivers seat, to 12 volt line at the refrigerator.
We turn of the refrigerator when pulling into a gas station.
The only problem we've had is to remember to turn it back on after leaving the station.
