I bought my truck with 40k miles on it in 2002 and it is still running like a champ.
I replaced the transmission after 150k miles, but that is the only major issue I've had with it.
I'm now at 235k miles on my truck and am having a hard time finding a new vehicle because I don't think I will ever get this type of value again.
Mileage is between 15.5 and 18 mph, depending on how I drive.
I have the 5.2L V8 (318) and couldn't be happier.
Change the oil, tires, and other basic maintenance and you'll have no issues.
Also, I've found through test-driving countless newer vehicles (cars and trucks), that most do not have as smooth of a ride as my truck does.
Reliability, power, value, does well in the snow for being RWD
My truck is 15 years old and has had one major issue ($1500 transmission change).
There's not much to complain about there.
