To continue with Bill's question... Unless you are going to put in A/C and/or a very large stereo system there is no need for a 100 amp alternator. In fact, if the ammeter in the dash carries all the truck current you may need to change it out or add additional circuitry to keep the needle from pegging.
When I die, I want to go peacefully like my Grandfather did, in his sleep -- not screaming, like the passengers in his car.
