Isn't that self evident? :R The fact remains that whether one uses six 6 volt GC-2s wired in series / parallel or three 12 volt G31s wired in parallel voltage drop under heavy inverter load will be less with the 12 volts than with the 6 volts. The second fact is that by using GC-2s which were specifically designed for golf cart use one is adapting batteries to RV use ... adapting, not using a battery specifically designed for the task at hand. ;)
What about dry camping for four days... only battery use is lights at night, and the water pump. Do you think two 12v for this application as well? What do you recommend for the best battery to buy?
