I run 2 red top optimas. I have a 140amp isolator. It is hooked to the alt, and it charges which ever battry is lower.
I have also had them tied together, and with just a switch for primary and secodary. I like the isolator best.
Definetly use good wire, I put o1 ought, the thickest guage I could get. Both of mine are under the floor, behind the pass seat. I have a battery kill switch in the consol. If you put one in, be sure to use the neg side, the pos arcs too much due to the amps and will damage the contacts. I also set up the wiring so one batt is just for running the basic truck stuff, the other is for winching and aux lights, ect.
