As usual, there are arguments both ways, the chance that the frig will try to ignite while at a gas station are remote, plus the fact for gasoline fuel, the stoichiometric air/fuel mixture is approximately 14.7 times the mass of air to fuel. 7% gas, 93% air. This may seem like an easily attainable amount of vapors but in fact it is unrealistic and requires an enclosed environment to achieve this kind of ratio. As stated above, gasoline vapors are 14.7 times heavier than air and will immediately sink to the ground and a refrigerator igniter is approx. 3' plus above the ground.

Those that believe in turning off the propane or refrigerators will continue to do so and those that don't believe in turning either one off will continue to leave them on.

With the thousands and thousands of campers traveling with the refrigerators on, we should be inundated with newscasts and videos of campers exploding at gas stations, in 73yrs, I've never seen even one.

X2. Especially diesel, but watch out for the guy next to you.

Plus, the refrigerator is 25'-40' from the gas pump.

The chance at being struck by lightning in a year are around a million to 1, but I'm not about to push it by running around with a metal pole in a thunder storm. Please, turn of any ignition sources when fueling up, especially if you have loved ones with you. Safety is more important than cold beers. Well, maybe not.. and yes it has happened. Gas vapors, ignition source, fire, camper burns up, fire impinges on propane tanks, relief valve starts screaming flame or worse.....KA-BOOM! (BLEVE) Was a cold fridge worth it? Even better, fuel up before hooking up.

I see your point since diesel has a much higher ignition temp but I wouldn't chance it since there are usually gas pumps close by. Gas vapors can travel considerable distance and "puddle" in low lying areas. All I'm saying is why risk it? It may be rare but it certainly isn't impossible.

if I ever pull into a fueling station and smell so much gas that there could be an issue, I will move on and call 911. Could always up grade to a 3 way fridge(propane,120AC and 12DC).
Every one should be safe and think of others

Sure hope you don't stop at a station with another camper fueling because his frig is probably on.

If you see a Sunseeker pulling a 16' enclosed motocross trailer, I know for a fact his is on.
