78 Bronco Custom, 460/ZF5, Sniper upgrade, 3G, dual batt
Love the dual setup. I put mine in primarily for the winch, but I run other stuff off it also. I just used a charge switch rather than an isolator. Also keeps the aux battery charged as needed. 0/1 braided cable between both batteries, and mega-fuses in between that. I got a couple of RuffStuff battery trays made for Optimas.
