Dual Alternators?
I am planning on buying an F-350 PSD, 4x4, CC, LB, DRW (but not for a while), and will be adding all sorts of things in the way of lights and such. I am wondering if having dual alternators is really necessary or advantageous. If so, should I get them as an option from the dealer (an extra $335) or install a second one myself?
Thanks for the help,
