I bought this truck in 2009 and so far have put 1000 miles on it. So far so good haven't had a problem with it yet. I'm not sure about fuel economy though, I have the 4.0L V6 and I get 14 in the city. I'm suposed to get 17 in the city and 20 on the highway. Other than that i love this truck. Its the best one That you can buy for the money. I wouldn't reccommend this truck unless there is only two people in your family.
smooth 5 speed transmission, 207 HP out of a V6!, 5,000 lbs of towing capacity, sport cloth seats, audio jack for ipods, fender flares, nice alloy wheels, and fog lights
