My 1500 HD is a beast on fuel. No matter what I do I can not get over 13.5 MPG. While I appreciate it's [power and towing abilities i did not expect to take such a hit on fuel economy. I traded a 1500 with the 5.3 which was getting 22.7 at highway speeds. Next time I will buy a Tundra which can tow just as much and when not towing get 18-20 mpg.
