 I've had the truck for almost one year now and I love it. It has all kinds of power with the 4.0, but will suck the tank dry very quickly if you don't take it easy. It is capable of 20mpg on the highway, but I find myself unable to drive slow enough to achieve that very often. The only other complaint I  have is the 6CD changer. It likes to jam up after it gets good and hot on long trips. The truck is pretty easy to work on, so I have no complaints. I only wish I had bought a 5-speed and not an automatic trans.
