Agree with Daytona on 1992 forward. I can't speak to the 4X4's but I've had two 5.2, auto RWD's.

First a '92 bought in Jan of 95 with 50K on the clock. Drove it until 2002 putting 265K on it. Very dependable! Engine and trans never touched. Replaced coil and water pump a couple of times, plus consumables including rotors and calipers around 190K. Starter at 230K. Mostly highway miles. Undoubtedly one of the best vehicles I've ever owned.

Second was a '93 bought in Aug 2008 with 145K on the clock. Previous owner said the transmission had recently been rebuilt. Drove it until October 2014, when I got my SRT at which time I handed it off to my daughter. We retired it last year when it began to miss and plugs and wires didn't fix it. I suspect the intake gasket issue, but just didn't see putting money into it. Coincidently, It had 265k on it too.
