Well, this past weekend I got to do my first semi long trip and tow with the V10.

I loved it. This thing would pull until the cows came home and never miss a beat.

I only got about 11.5 on the way down, but coming home I got 14.6 mpg.

I can only attribute the difference to the head wind I had on the first part of the trip. But I love the way this truck pulls. I probably won't ever tow more than about 5000-6000 pounds, so I opted for the v10 over the diesel and am glad I did. I also have the 3.73 gears, not the best for towing heavy loads, but I could climb some pretty steep grades in overdrive doing about 77mph and the truck would never down shift and only fall to about 76 mph.

I just wanted to post my real world obsevations to let anyone know what they can expect. I always hear the mileage debate going on and so I wanted to share my expereince. I don't really care about mileage and this will probably be the only time I will ever check it, but with all the debates I wanted to see what I would get. I also drive with my foot on the pedal. I dont baby the gas, I move out when the light turns green and I love it.

Just for the record, my truck is a 2002 F250 CC v10 short bed lariat with 3.73 LS and 4x4. It is also all stock with about 1700 miles now.

Thanks

I have never gotten 14+ mpg towing, but i have seen 11+ towing an 8500lb travel trailer.
We towed from South Jersey to Lake George last year and logged 11mpg to 11.8mpg while towing .
Ive got a 99sd 250cc V10 with a 3.73 ls and auto tranny.

I intend to order a new sd truck this spring and im going to get the 4.30 axle because i have found that in order to keep the tranny from bailing out of od you need to be doing about 70 in hilly terrain.with the 3.73. That gets a little wreckless when pulling 8500lbs.
You shouldnt have any problem with 5000-6000lbs with the 3.73.
good luck with your truck!:-)
