I know Fords get a lot of ribbing, but my 1992 4WD Explorer Eddie Bauer had close to 300K when I sold it to a young guy who wanted to restore it. Granted, this was built on the Ford Ranger platform - a real body on frame pickup - so the pedigree was fairly predictable. My opinion only from experience - Ford cars suck, but they do (or at least used to) build excellent trucks.
That said, the 4.0 liter V6 ran on a variety of oils over the years - Quaker State 5W-30, Shell Rotella T-6 5W-40 and Supertech 5W-30, even NAPA/Valvoline 5W-30 for a while. Had an EGR valve go wonky, and a PCV valve replaced. The transmission, transfer case, front and rear differentials got regular fluid exchanges. Other than the usual brakes, tires, shock absorbers, spark plugs, oil/filter changes - it was a great vehicle on and off road (and it got quite a bit of time off road). Many a trip it got 'rode hard and put up wet'.
