The new trend is to go with 24 or 48 volt batteries. and step them down to 12 volt. Smaller wires. I personally would not do that. If the step down does not work you would fry the RV
A desirable upgrade might be replacing two factory installed 12 volt “Marine/RV” batteries wired in parallel, with two 6 volt golf cart batteries wired in series. (If they will fit in the space.)
and if they will fit (and I have never seen a 5th wheel where they wouldn't) a Group 31 size 12V battery would be preferred as it's slightly larger size can provide a little more power. UH UH!
