That would depend on how the wires are connected between the battery and the
fridge.... stock is typically run through a fridge relay that disconnects
the fridge from the starter battery when the engine is not running.

If the fridge had run overnight on 12 v and connected to your starter
battery you definitely would not have been able to start the van in the
morning....
On the other hand maybe... if the propane kept the fridge cold (or if the
weather was so cold that the fridge didn't need any power to stay cold) then
the thermostat would not be calling for much in the way of 12 volts... like
I said it all depends on how the fridge is connected to the starter battery.
