We still have ours. 1999 about 190,000ish miles on the original motor/trans/transfer case.
Most repairs have been piddly crap:
Battery and Alternator maybe $200, that was a long time ago.
Heater core, did myself for $100 in parts, had an estimate for $700 at a shop, it is labor intensive.
Put in a new radiator/water pump/belt/thermostat for about $400 in parts.
Had a recent $500 tab at the shop for brakes all around (needed a couple of rotors) and some worn out front end bits.
That has been the worst of its repair history, other than that its been a great truck. It does only get about 12-13 MPG, but ours is pulling 32" tires with 3.35 gears, so the motor works pretty hard to get it around. It has the 5.4 liter motor, and has a little valve rattle on a cold start, but that goes away in just about 45 seconds.
