I picked up a perko dual battery switch. Since the battery in my trailer will be only for the trailer accs, I can't see running some giant welding wire to the battery and I only had an 8 ga for my old travel trailer.
What is the best size wire should I use off of the Perko 3 way selector to jmy battery in my trailer so I can charge it when the rig is running?
