I have driven this truck for over a year now, and I have put over 35000 miles on it. Great truck to drive and also very fun. I have pulled over 16000 lbs in a gooseneck and it did perfect. The transmission is EXCELENT. Saves the brakes when hauling. With a K&N air filter I get about 13-16 GPM, with 265/75/R16, and a 1.5" front end lift it looks great.
