And I would only use them with the inverter for the fridge when traveling from one destination to another. No dry camping at all. Am I making sence now. I hope I hope.
I think your question has been answered in one of the latest posts! I would think the 2-12 volt would be sufficient, however you have to keep in mind that those batteries are also used for house power, lights, fans etc. I think?? We don't have a residential fridge in our fifth, and we travel with the fridge off, and at times drive for 6-8 hours a day and the contents remain cool and frozen! Now maybe our temps 75-85 aren't as high as were you will be driving and that could make a difference! Experiment is the only way to know!
