Can an RV fridge run off battery? | The Savvy Campers 

I have an old truck and Lance camper (80s) I added a 200ah lithium battery, two 100w solar panels with a charge controller, and a 3000w inverter. When I travel long distances with my fridge running off the inverter, it kills my battery. I'd like to add my truck's charging system while towing through the existing 7-pin connection that has a 10awg wire available in the engine compartment. It has a 120-amp alternator and dual AGM batteries. It needs to disconnect automatically when the truck is off. What do I need?

i have a coachmen catalina. do you know if i can switch it to battery bc i was told it can only do propane

Thanks

How long do your batteries usually keep your fridge running off gas.

I live in my RV and i have a propane or electric refrig. I do not use my propane due to a leak. So my refrig stays on electric. Does it need the rv battery on in order to work

But how do you tell the fridge to run off the battery?

Our fridge status goes into check when we use the 12v baterry only. ¿What can we do to run the fridge with 12v battery only?

I have two 12 v batteries and my fridge is not running well

Very confusing…😮 does your fridge run from just battery power ? I understand it can run from propane and AC power, but what about just pure from DC battery power?

Can someone tell me how use my 110&propane fridge on just 110. How to get it to use just the 110 and stop using 12v on it brand is dometic it keeps draining the battery, the fridge by itself nothing else. And then it kicks on the igniter. Plz help anyone with advice.
