I've got an 01, and what has been said so far is true. 21 Mpg, bad intake gasket, fuel pump and whel bearings. One other oddity is that the rear diff vent tube. It is run up under the bed. Since the crew cabs have a short bed, the vent ends up hanging in the open between the cab and the bed. Over time, some of them suck water in the vent. I had to put a pinion seal in mine, and discovered about a half an inch of water in the bottom of the diff. I was racking my brain trying to figure out how the water got there, until I finally found a reference to the vent tube.
