The 12 volt AFAIK was originally used for traveling. It is 100% safe and
doesn't cost anything. Yes propane works better and it will stay lit
while driving, but it is or can be dangerous if you are in an accident.
While driving your propane should be turned off. I don't remember the
expansion ratio for sure, but I think it is around 300 to 1. Yes the
pressure relief valve works great when the tank is turned off but if the
tank is turned on and the line is ruptured you will have an explosion of
unbelievable size. One pound of liquid is equal to 300 liters of vapor
and in the right mixture you have a good size fireball. Add to this the
fact that you are carrying 65 liters when full and add a 30 second or so
time delay before it ignites and you have a fireball burning at approx.
1500 degrees the size of ten gmc's square. That's why you are supposed
to drive with the tank shut off. The explosive range of propane is far
greater than the expl. range of gasoline which makes it far more
dangerous in a fire.
After having said this I have to admit that I also drive with the
fridge running on propane.
A good thing to check is to find out if your insurance will cover
you for fire if you are driving with the valve on and the fridge
running. Maybe you can turn off the valve after the fire to fool them,
but I doubt it.
