The day before we leave I switch the fridge on to electric, just before we pull out I switch to propane and that stays on till we reach our destination, then it goes back on electric until we leave the campsite to come home or go to another camp site then it's back to propane, until we get where we are going I don't shut it off when we get gas a meal or any other reason until we get home. Seems like scare tacktics like not filling a plastic gas container in the bed of a pickup because you might get a spark, It's plastic how is that going to cause a spark?
