Thanks, PeteandJoan. I installed a knife style cutoff switch shortly after getting the rig since the convenience center cutoff doesn't actually cut everything off and the other cutoff I have is specifically for the refrigerator inverter. Put it on the negative terminal.
Since you were replacing 2-12v batteries with 2-6v batteries, do you feel like the change was worth it? In other words, do you notice a difference in how long the batteries last compared to the 2-12v batteries you had? I'm having a hard time justifying more than double the cost in my mind.
