I've owned my 2004 4X4 quad cab 6-speed manual for three months now. I bought it from a private party about a 5.5 hour drive away. I carefully calculated the mileage on the trip home... it was just a shade over 21 MPG. That was driving the speed limit... 65 MPH on the interstate & 55 on the state highways. The mileage drops to about 16 MPG when towing a three-horse trailer with my daughters' two horses inside. I'm sure that's better than a gasser would do.
