I am refreshing an 02 SXT right now. New fenders and arches above rear wheels.
140k miles. 3.9. Guy has had zero sludging problems because he changes every 3,000.
On the other hand, my ex-FIL (I got him in the divorce) has an 06 3.7 Dakota and it was sludged. We are going through a process now where we used a quart of the anti-sludge right before an oil change. It must have been a long build up as that stuff is still coming loose two oil changes later. Suspect it's just the additives in the fresh oil breaking it down.
Edit: On the 06 what tipped me off is I could hear valve lifters clacking.
