Well first check and see what you have. Secondly these newer trucks have a lot more electronics than older ones so that mind set it worked before won't cut it.
Check to see if there is a bigger alternator from the heavy duties you can get. Otherwise just let your finger tips do the walking and see what you find on the internet.
