As is the case if one has lot of money then everything is subjective they can get what they want.
A very large percentage of van users use LiFeP04 with some kind of inverters and you are just talking about a small specialized group of users.
I just want to reiterate unsuspecting customers that a dc-dc charger is NOT a requirement to charge your LiFePO4 through your van's alternator and gives no added benefit than what they already have if they are resourceful.
It depends a lot on the brand and model year.
Modern vans have smart alternators, and you are not in control of what that smart alternator is doing voltage wise.
