Come on people, some of you people worry too much. Think about it, thousands upon thousands of all kinds of RV`s on the road and I have NEVER heard of one burning down due to filling gas tank and catching on fire due to the fridge being run on propane.
I would believe that motorhomes would be way more prone to this than
fifth wheels and travel trailers due to where motorhomes fuel cap is and
AGAIN I have NEVER heard of a motorhome catching fire due to running fridge on propane and fueling up.
If you are going to worry about this you had better be shutting that cell phone off that is in your pocket because it can also cause an explosion while fueling you vehicle. LOL
