I have a 5er that came with a single 12V RV battery. I am thinking of replacing it. What I don't know, given the same amperage, would I get better service from 2 12V batteries in parallel or 6 6 V b...
I think the first question should be "Do you need the extra amp hours that 2 6 volt batteries will give you?" Do you plan to boondock often or have an inverter to run or do you usually camp with hook ups? If the need is truly there then 6V has the advantage. We very seldom if ever camp without hookups, don't use an inverter, so I have no need for the extra amp hours or weight.
