I have seen number of RV's burned to the ground since 1974 when I started RV-ing. Truck campers, trailers, motorhomes. I didn't know the reason for the fires. Could have been caused by released propane from overfilled tank, could have been gasoline leak from old&cracked fuel hose, could have been from number of reasons. One trailer fire was caused by a cigarette butt thrown by a driver which landed in the trailer he was pulling. Yes, bad things can happen in an accident. We have to carry fuel, be it gasoline or propane or natural gas or diesel which is a risk factor all ready. Propane, when leaking tends to collect close to the ground because it is heavier than air. My point is why to increase the risk of something bad happening by having an open flame while driving. DOES THAT FRIDGE REALLY HAVE TO BE ON WHILE IN MOTION?
Yes, just ask my DW who is a food safety manager. The insulation in an RV fridge isn't worth squat. Bacteria is always growing in your fridge. The warmer it gets, the faster it grows.
The problem with your argument is the dangers you suggest are not specifically related to the motion of the RV. A propane line can break any time. Even if the motion of the RV broke the line, if it were possible to have a large enough concentration of propane around the fridge flame to light it, then when you turn your fridge on, once you stop, you have the same hazard - technically you have a worse hazard because had the flame already been burning, it would tend to burn off the fumes faster than they would build up. Your fridge has vents. As you point out, propane is heavier than air, which is going to make it run out the lower vents in the fridge compartment.
