6 volt battries

Hi all;
We have a 34' motorhome and the 12volt coach battry doesn't seem to do the trick. I have heard that two 6 volt works better. Does anyone have information on where I can get 6 volt with plenty of crank time and amps?
Thanks for any input :cool: :cool:

You may want to try trojans 105 or the newer 125's. Truly a deep cell battery, just watch your water level and charging times as not to boil them dry. I purchased mine from a gold cart sales company as that is what they use in there golf carts.
