Overall this truck has surprised me. I'm a Chevy lover and yet i like this truck. Very comfortable and great on gas. Despite i have the two wheel drive version it love the mud. No major problems with it. 189,000 miles and still going strong.
I bought this truck new in '94 and I used it every day for 10 years until I got a family minivan. I have towed concrete mixers, hauled scrap and lumber, use it weekly to carry stuff to the dump. I carried the kids in the extended cab (when they were little, not a lot of room there.) The truck never let me down and today I still have it (though it's semi-retired)and use it 3-4 times a month to go to the dump. It has 167,000 miles on it and now my daughter just got her lisense and she drives it daily to school and about. It still gets 22+MPG. Never did more than routine maint and replaced the clutch 2x. What a great investment in 1994!
If you want MPG, go for 4- or 6-cyl with a manual trans, and avoid 4 wheel drive. I bought this as a 3rd owner in 2016 with 112k and the only thing that didn't work was the cruise but got it fixed(adjustment cost $40). I keep it around 2500 rpm, windows up and A/C on, and get 25 mpg. The arm rest clasp is broken so it stays closed with velcro. The paint is holding up great and has no body damage. The interior was very clean. It handles well, rides smooth, and brakes easily. It does not accelerate quickly, but that's another gas saving feature! I can tow my filled 5' x 10' trailer like it's not even there. If I could improve it, I would make the side view mirrors bigger and relocate the cupholders.
UPDATE: Dec 2016: I have gone 5000 miles so far and everything is going well. I replaced the headliner and the cruise control stopped working. Otherwise, the truck drives as it should and hauls as well as it tows. It even went off-road into my back forty to pick up some trash and debris!
I had this truck handed down to me from my dad, who has had it from 1996. He bought it from a private owner with 20k +/- , with the cruise control already not functioning. This has not bothered me though, I put about 30+ miles a day driving to school and back. My MPG stands at about 18-19 city, 22-23 hwy with the 3.0 V6. There have been no major issues with the truck, just routine maintenance, such as oil, brakes,fluid levels, etc. There is a oil leak at the universal joint, but its not major. at 110k, It is still going strong and I do not intend for it to quit today, or for that matter, a long time.
This has been the best vehicle I've ever owned. After 157,000 miles (mostly commuting), I've not had a single mechanical failure. My only expenses have been maintenance. I drove it on a 12 hour trip and it was as comfortable as any car I've ever driven.
