    You pulled that trailer for a whole tank or just around town? Hard to get an accurate mileage (not using the overhead computer) if you do not pull that trailer a lot.

    My 2000 Durango R/T musters around 12mpg towing 2K. 9-10mpg towing 5-6K with the 4 speed auto and 3.92 axle. Empty in city I get 13-14mpg, highway varies depending on speed but my best tank was 18.3mpg at 55-58mph (not using cruise control).

    I have a 2003 Silverado 2500HD with the 6.0L engine. I don't even check my mileage...I know it's horrible. Just the cost of doing business to me. I need a truck that will tow 10K and couldn't justify paying $6k more for a diesel, so I just accept it.

    My old work truck (15L DD), I couldn't care about mileage. When my Durango does double duty, checking mileage is more than a number, in terms of cost, it also tells me if my mileage drops exponentially that I could have a mechanical problem and look it into it before it gets worse. When I went from my 13-14mpg empty to around 7-8mpg empty. I found out I had two problems; o2 sensor shot, and I had a bad injector. I wouldn't have known otherwise until the vehicle drove rough enough to illuminate a check engine light.

    I filled up, hooked the trailer up and towed it 20 miles and filled up again. I calculated it myself and it came out to be 8.02 MPG. I know its not accurate, but its pretty damn close i know that. I have the 5 speed Torque shift transmission with 4.10 gears.

    2004 F350 4x4 Crew, automatic, V10, 4.30 gears. It get's between 8.5-9 mpg towing about 2500lbs, entirely around town. My average speed on a given day is usually about 22mph. Lots of stop and go. On more open road I have seen over 11mpg towing an empty car trailer one way, and a loaded car trailer back. Stop and go is the killer.
