Yep, the Dana 60 is the 4500lbs version, while the 3500lbs is the Dana 44.

You might also look at "W300s" and D600s and such.  Those would "all" have
Dana 60 fronts, while I think the W200s with Dana 60 fronts are "rare"
(just like some rare 78/79 Ford F250 "SnoFighters" got Dana 60 fronts, but
otherwise the F250 got a Dana 44, F350 a D60)

The Dodge vs. Chevy rotors are slightly different, though I don't remember
the details.  I was comparing a Dodge D600 Dana 60 rotor with a Chevy K20
3/4T 10-bolt front rotor.  Overall diameter was the same, when I used a
cheap tapemeasure.  The Dana 60 rotors were thicker, though, which would
help prevent brake fade under heavy braking with a big load - precisely
what I would expect from a 1T truck.

> I doubt if my calipers will accept thicker rotors.

If you have the 4140 "extra"/heavy-duty brake option, you should already
have the 'thicker' rotors on the truck.

Dodge might have used a thicker 3/4T D44 rotor than Chevy used on their
10-bolt.  I've never had a Dodge 3/4T front handy to look at.

I don't have anything on the "depth" / hat / offset handy for any of 'em.
