I bought my truck (4.7 2wd quad) new November 2000. I get 24 highway and 18 mixed driving. I have a camper shell on it so maybe that helps with the better mileage as compared to other postings. Over these 9+ years I have had one window motor, Oxygen sensor, air- bag sensor go out, about $900 dollars total from the dealer. No other problems with the truck so far.
