Don't rule out the alternator or regulator yet.The parts stores buy the foriegn made stuff and it's not uncommon to get a bad one that's new.Charge the battery then put a test light between the ground post and the ground wire.If it lightss up you have a battery drain.Pull each fuse until the light goes off.This will tell you which circuit is draining the battery.Since you seem to be fairly new at electrical troubleshooting you will probably need help from this point.
You can also start the truck and check the voltage across the battery posts.You should be getting about 13-14.4 (approximately). volts while running and charging.

Maybe this will help you get started in the right direction.
