Our RV is motorhome so I don't have a "dog in this fight", but I have a dumb question regarding a 3-way refrigerator negatively affecting the trailer battery(ies) in it's 12V mode while traveling: Why not use the refrigerator in it's propane mode while traveling? (Just like what happens with our motorhome's 2-way refrigerator.)
A lot of people do that. But the theory behind the sale of "3-way" RV fridge products involves a safety risk: The concept of an
open flame is a bit like smoking at a gas station. Other people are refeuling (and perhaps spilling over their lawn-mower gas cans) somewhat near your open-to-the air burner; the fumes could create a fire. Some tunnel operators have a similar issue with the possibility of starting a fire after a gas-tank crushing accident. (Fuel spills on the roadway and doesn't dissipate within the closed environment -
you add flame, and BOOM!)
Propane mode Fridge "burners" are
never going to be caught on the road in motion - you would need to be pulled and stopped for something else before any "official" could even detect the issue. And whether they have actual laws against this is another question. But risk of igniting spilled gas is the concept behind the products - it's NOT about "blowing up" your own propane tanks.
