So much incorrect info regarding the furnace and RV style fridge and worries about gas flowing if they don't stay lit

The furnace and the fridge will both go to LOCK OUT mode if the control boards for each don't receive feedback indicating a flame is present..

Lock out mode has to be CLEARED by turning off either the fridge or furnace and starting again

That means... NO LP FLOW..

Suggest some read the manuals on how these appliances work ..

Bad info just adds to the confusion for some RV owners..

I have towed probably 100K miles running LP fridge.. I have also towed with the furnace ON when I got caught in unexpected freezing temps ( 20 degrees and colder )...
