Hi. Was just at the dealership planning to order my F350 6.7 Turbo DWR extended cab Laramie in May. My 5fer is a Carbon 348 with a GVWR of about 17,000.

I have a question about a few things:

4.1 or 3.55??? Which is recommended and what exactly does this decision effect?

Alternator choices: any reason to order higher/heavier duty alternator?

I looked at the payload on a 2021 F350 Laramie DRW on the lot and it was about 5600lbs.
