6v vs. 12v house batteries

Only if you NEVER rely on battery power when boon docking. I have 4 golf cart batteries and can along with my solar panels boon dock for 4-5 days even on cloudy days before I need to use my generator. Previously I had 4 12 bolt batteries and had to use the generator every couple of days under similar circumstances.

My opinion is no way would I change back to 123 volters for house batteries.
