Does anyone have much experience with the electrical on these setups? I'm not real familiar with the bank battery idea. There is a switch on the dash that the PO installed and said it was to charge the bank battery while the truck is running. Other than that I know very little. I found a real sketchy homemade male to male end extension cord in one of the side storage compartments that is going straight in the trash. I'll just keep doing my research and am sure I'll figure something out, I just thought I would ask the question.
