17k on this FF ... magnet could not hold anymore

Mopar had moved to synthetic in the early 2000's ...
FWIW Ford called for 75W-90 in the 2000s and switched to 75W-140 after they started losing rears under warranty.

I'm not sure how many miles you currently have on your Ram or when the rear diff is officially broken in but if yours is fairly new with low miles I'd wait a while yet before switching over to synthetic or even changing it out if it is conventional unless you plan on doing it again in another year or two?
Many vehicles out there go their entire lives without ever changing the diff fluid out so changing real early shouldn't be a priority unless you know for sure the diff(s) are fully broken in. Just my opinion anyways.

All Chrysler fluids for Diff/Transfer case and transmissions are synthetic now.
One thing to note it says "If Equipped" for limited slip diff. in another part of the manual. So you need to find out if you have this in your vehicle and if so make sure you get a Limited slip fluid or add the additive for this type of diff to a fluid that doesn't already have it in it.
As for when to change it I would wait for at least 10,000 miles before changing it out to allow for break-in wear to occur.

I appreciate the replies. I'll change it out at 10k. Good advice on getting rid of the break in particles. It does have the limited slip diff so I'll get the additive as well.
The owner's manual says mopar synthetic. Anyone know who makes their oil? Just curious.

Shell makes their factory fills but Valvoline makes their coolant so it could be either, not really sure. It's good stuff whatever it is because my neighbours Ram we changed out the factory fill Diff fluid at 100K and it was fine. Lots of filings though.
