Traveling with Propane on

Always.

Theoretically there is a very slight chance that while filling up your and your RV was sitting next to a gas pump and the refrigerator vent panel was very near that gas pump hose as it was pumping gas and the wind was exactly right to lift the heavier than air gas fumes up and blow those into the refrigerator vent and the refrigerator was currently cooling and the fumes reached the burner, then yes, a fire is possible.

Likewise if someone sprayed gasoline into the refrigerator vent while it was on ………..

Diesel fumes are not explosive like gasoline fumes. Diesel is more like charcoal lighter fluid as far as flammability.

We shut off any appliances using propane in our motorhome when refueling to prevent the ignition sequences from possibly igniting gasoline fumes, but not the tank itself. With a trailer, the distance from the fuel fill point pretty much negates any danger risk. We no longer have an absorption fridge, so no propane needed there, but we do run our two propane furnaces as needed when traveling in cold weather. We also use the stove at rest stops to make lunch sometimes.

I leave the refer in "auto". We run with the propane on.
Turning off propane is a safety item when refueling. Chances of enough build up to blow up would be very minimal. Not saying not to do it or to do it!

Safety first!!

What is it about fueling up that makes you want to shut off the propane?

When I had a trailer, the propane was always on until it needed to be switched or until I put it in storage. Now, the only time I turn it off is when refilling the tank.

Thank you. Have you ever had to relight the stove to make sure propane was still flowing to the fridge? One last question, at home do you start off with the fridge on electric and then switch to propane when you leave ? Or just start off with the propane at home before you leave? Thank you
