And what you might imagine is likely MUCH worse than reality.
When that reasoning is carried to it's extreme it becomes: It is not safe to even CARRY a propane bottle on/in a vehicle.

There will not be a major problem unless the system ruptures at or near to the tank, before the first regulator. The odds of that happening are extremely low because of the factors already mentioned.

The 'highlighted' statement is always used as a reason to NOT use propane while in transit.

Fact is RV Propane Systems have MORE integrated safety features/designs then the fuel system of the vehicle being used.
Excess flow trip device, thermal bushings, spring loaded shutoff valves, flame proving, failure 'lock-out'.

"Nothing to fear but fear itself" ....as one from long ago so elegantly stated

IF the propane system features/safety devices are not sufficient for safe operation of an LP Appliance while in transit I would not use it while stationary and asleep

YES.....you can operate the fridge on propane while traveling

Same for furnace (water heater also if there was a need for hot water at rest stops or immediately upon arrival)

Propane appliances have safety interlocks and the propane system as safety features ---all of which truly minimize propane dangers.

I have always used the propane unless I decide to run the generator for the roof air, then it's on electric anyhow.

Actually, next season, I'll relegate the necessary to be refrigerated and frozen stuff to the Dometic Cool Box I am going to buy this winter and leave the fridge off when travelling. The Cool Box will reside on the back seat of the truck until I get to where I'm going and then I'll fire up the RV fridge and load it with the pre-chilled and frozen stuff from the Cool Box. The Cool box is much more efficient that the fridge is plus it will be more handy in the backseat versus in the camper.

:h I think I'd save the money for repairs if needed for the fridge, nice to relax when I get to the camp, not to continue loading the trailer.

Fridge is turned on the day before we leave and is never turned off until we return home.

Being new at this, you might want to consider which sub-forum you put your posts into in the future.

A refrigerator question doesn't fit too good in "Roads and routes"; having it in a better place might get you more/better answers....in general.

The YES answers are correct. The "standard" recommendation is that you shut it OFF while re-fueling, either the chassis fuel tank OR the propane.

35 years RVing, fridge on.
