Converting 12 volt coach batteries to 6 volt
I have a 2000 Tiffin Zephyr. It has 4 deep cycle 12 volt batteries that power the coach. The batteries need to be replaced. I have heard that using 6 volt batteries is a more efficient and economic...

I have 2 solar set ups in our trailer in the mountains of New Mexico. The original 12v 'marine' battery didn't last a year, when I switched to 2 golf cart 6v batteries from Sam's, they are still going 5 years later despite a bad incident where the solar controller shorted out and the batteries went down to nothing during the winter. They revived and are still working. In the workshop, I replaced 6 2v industrial batteries that were at the end of their life with 4 sam's club 6v's and have been very pleased with the results.
I believe the difference are that golf cart batteries simply have to hold up to being deeply discharged, and the marine batteries have lighter plates. But, I get the logic that the amp hours of SOME 4x12v batteries and 4x6v's will be about the same. On my motorhome, I could only replace the 2 12v's with certain (Chinese) AGM's put on their side, because of the tight clearance in the battery box, and don't want to extend all of the connections to another battery location......yet. My stock RV batteries are spec'd (75 ah each, 150ah both, at 12v) below the wet cell 6v duo (200+ at 12v) in my case, anyway, so I'd switch in a second if I could.
