 Bought used w/ 70k miles, so far almost 30k miles later and still loving it, the only mechanical problem I have had was the small part in fuel pump (unfortunatelly I had to buy the whole unit $560 w/ repair). Nothing else done to the engine or the truck itself. I live in snow country - the bottom is rusty or should I say rustic... That amount of salt will eat alive anybody. Great comfort, great tow, perfect in the snow, 4x4 is fun to drive - I highly recommend to anybody. I've seen models w/ 160k miles on them - the only thing - do not put syntetic motor oil, I noticed lesser performance... Not sure how it is possible, but the truck works better on regular oil... It's a keeper!
