My refrigerator does not have an "open" flame. The burner is totally enclosed.
It is also at least 4 feet ABOVE any fuel vapors (such vapors are quite a bit heavier than air).
It is also on the other side of the coach and about 8 feet forward of the fuel filler.
It is nearly impossible for any explosive vapors to get anywhere near the flame.

Interesting. The BC government approval sticker for my 5er's propane system located right next to the bottle compartment, specifically states that the bottles "shall be turned off when the vehicle is in motion". Folks might want to check their local regs to determine their liability if something goes boom with the system turned on. Just sayin.

Watching too many action movies again I see... CGI explosions are making these myths even harder to dispel!

It takes a very specific mixture of fuel vapor and air, along with a spark or flame, to make an explosion. Too much/little fuel, no bang.

Pretty much all gas stations are clean and leak-free these days. The cost of a spill is way too high. There's very little vapor floating around from actual fueling operations. Any breeze at all disperses it, even just from moving traffic.

Your fridge flame is inside an enclosed flue inside an enclosed compartment with limited ventilation. It would take a long time sitting in dead air for the vapor to seep into the compartment and get to the flame.

Can the right combination of events happen and cause a boom? Sure, but you almost have to set it up on purpose to make it happen, ala Mythbusters.

I cannot drive with my propane system online. As some may know, to get out of the Virginia Beach area you have to pass thru a tunnel or two and it is mandatory that all propane be secured prior to entering a tunnel. They do have propane check stations that are madatory for all car/trucks with bottles.
With that being said, I usually let the fridge run the day before we leave on a trip that way everything stays cool during transit, and after a 6 hour day of driving the contains of the fridge and freezer are still good.
So, back to the OP. I dont run mine while driving, but if I did I would probably turn the propane off. Why risk it when it only takes a couple of seconds.

Ever since I first drove through one of those tunnels back there, I have wondered...
What do they do with propane powered vehicles?

I turn mine on when I leave home for Florida in Dec and turn it off when I get home in April, drove close to 40,000 with it on, never turn it off when away from home.

Obviously, you were not in an explosive mixture, close to an ignition source. you are still here to post.

Yes, I am about the same height, and I have smelled gasoline fumes while fueling, especially if I am standing right next to the nozzle while gas is going into the tank.
However, I often do a walk-around while filling the tank, and I have NEVER noticed any fumes on the OTHER SIDE of the coach, near the frig!
In fact, I don't recall ever noticing any fumes or gas smell when more than a few feet from the filler!
Gasoline vapors are much heavier than air. They will drop to the ground very quickly, and stay there, always flowing downhill.
