Matt,
One of the guys on the Ford owners’ website has a 2020 F350 with dual alternators and he metered 14.1 amps to his batteries from his truck. I don’t know how much difference having dual alternators makes as I have no experience with that.
In my experience the amp output from the truck can vary a great deal between trucks.
