Just what to know the Amps for the stock alternator in my truck listed above. Amp output while running at idle with no A/C, radio etc., on.

Hello,
Depending on the factory options, these trucks come with either a 130-amp or 140-amp alternator.

See attached for the factory provided alternator rating.
Let me know of any questions.
Thank you.
