Ok I need to get a new alternator for my truck. 2004 F250 6.0l turbo tiesel. Currently it has a 110amp. I am thinking about stepn up to a bigger amp since with plowing this turns to crap quick. What amp do you guys suggest and is there a good place online to order. Every place I call locally only carries a 110amp. Also it is the single alternator setup. THANKS!!
