dometic dm2652rbx refrigerator- cooling in travel mode

[addacrash]

Good afternoon- I have had an annoyance with my Dometic DM2652rbx refrigerator. My fridge only cools while connected to shorepower or by propane. While travelling, my only source to cool the fridge is propane. Which on mountain roads or heavy wind, seems to every once in a while snuffs the flame and my family in the cabin smells propane. So if I turn the propane off at the cylinder, this smell in the cabin does not occur. However, my fridge does not cool.

Am I missing something as to why my fridge does not work on batteries or alternator while in travel!?

I have attempted to ask RV dealers, but their best answer is to run the generator while travelling, which left me dumb founded...

Is it possible to use batteries with this fridge while in travel? If so, how can I go about doing so?

Thanks for all direction I may receive. I just cant believe propane is my only option while in travel!

You'll need an inverter.

If you have a 3 way fridge you could run on 12 volt while traveling and have the TV charging system supply enough power to the batteries to run the fridge. Never had my propane flame fail during travel. Extra wind deflectors around the flame?
