Yes, I'm regenerating a 5 year old thread. With my new 5th wheel and six 6-volt batteries, I'm finding that the truck does a poor job of charging the RV batteries. Before my next trip in the spring, I'm going to replace all the incandescent lights on the truck with LED's and am doing research on either a dual alternator setup or one high amperage alternator. Does a dual setup cut into fuel economy? I'd appreciate any input that anyone could provide. One thing that concerns me with the duals is 'dealer programming'. With the work that I've done, I don't want a dealer programming anything on my truck. Is programming a must? I'd like to just install the extra one for charging trailer batteries. Run a 8 gauge wire from the output, through a circuit breaker, to the distribution panel for my batteries. Again, any input would be appreciated.
