This has certainly got me thinking. I have an Aliner Expedition and wonder, if turning the fridge off, it is necessary to pop up and go inside to manually turn the fridge off, or can I simply turn of the propane tanks from the outside and that will be enough to cut supply and satisfy the need to "turn off the fridge"?
You should turn it off inside. There's no need to close the propane tank valve when refueling the vehicle; the concern is the open flame in the fridge, and the sparks from the igniter.
As to how much of a safety hazard leaving it on is, I won't venture to guess. However, in most if not all states, it's the law to extinguish all open flames when refueling, so it seems to me it's a moot point if one wishes to operate on the up-and-up. Likewise, it may not be very much additional danger to leave the engine running when refueling (particularly modern vehicles with solid-state ignition systems), and putting gasoline into non-approved portable containers may be perfectly safe in many cases, but it doesn't really matter because the law generally prohibits those activities as well.
