I've got about 209,000 miles on the 5.0 liter V8, and still running strong. I had to replace the transfer case at about 150,0000, but I was pulling a trailer a lot, often pushing the limits of what the vehicle is rated to pull. It's still my daily driver, and couldn't be happier with the longevity, and what I've gotten for my money. No, it doesn't get great gas mileage, but it's a 4500 lb vehicle with a V8 engine, what do you expect?
All Wheel Drive is awesome in the winter! I've never had a problem in snow, and pulled a several cars out of ditches.
I'd say more power, but they've already done that on newer models.
