My truck came from teh factory with a 7 pin trailer connector. One of hte pins is to charge RV batteries.
Anybody hook up their boat batteries to this pin? If so, what will it take to make it work? DO I need some sort of charge controller or does the truck already control the charge to teh RV batteries like it does for the truck battery?
