"philandmargo...."wildtoad" and "tiredkid" have the best answer. Even though four 6 volt batteries are typically what are now used by most, the 12 volts are fine if they served you well. Since you have to buy batteries anyhow, the cost of batteries will be a wash, but with the price of copper cable, you could spend quite a bit of money on new cables.

I understand that we are all just voicing our opinion, but that opinion should have some basis of fact.

Seems to me that one could re-use the interconnecting cables from the four parallel 12V batteries to interconnect the four series/parallel 6V batteries AND HAVE TWO CABLES LEFT OVER... Where's the big investment in new copper cables?

Because he needs 8 six volt batterys to make the same power as 4 12 volts(approx.)

Sorry, Not true.

ok explain your opinion. mine is I see 4 12V batterys at 215amp X4 = 860 and 8 6 volts at 225 per pair = 900 so pretty close?
I do know for sure your theory of Four 6 volts will = four 12 volts is wrong

You are comparing apples to oranges. Not too many folks have 215 amp hour (at the 20 hour rate) 12 volt batteries installed.

You have to define which 12V battery you are comparing to which 6V pair. Obviously two $350+ Crown or Trojan 12V batteries would outperform two regular GC-2 6V batteries, but The standard 12V deep cycle hybrid marine battery that you are going to find in most RVs will be about 105-115 AH. Compare them with the popular and affordable T-105 @220 AH 6V and repeat your math exercise.
