residential fridge with ice maker

[rkelley712]

i have a 2020 jayco precept 31ul and it has a large residential fridge with water and ice in the door. when i boondock the batteries go down within 36 hours. I have two deep cycle 6 volt batteries. My fridge being a residential fridge does work on propane or 6 volt only ac. Any options out there that would help not running my generator alot. I thought about 2 deep cycle 12 volt battiers as an option..Need advice....thx

I would consider solar if you have a clear view of the sky where you boondock. You'll need enough to charge the batteries completely each day from the overnight draw. If that's not an option, then switching to 12v batteries in parallel may help, and I would consider lithium batteries as well.
