I actually get pretty decent mileage (relatively speaking) with my Excursion, which has the 2-vavle configuration 6.8L V-10. 13-15 mpg highway and 7-9mpg towing a 24ft Haulmark full of car. Not bad for a 7000lb vehicle.
To me torque is a bigger issue than mileage if you're going to use it for towing. While the older 2-valve has 425 ft/lbs and the new 3-valve has ~ 450 ft/lbs, that just isn't enough to pull the vehicle itself much less tow another 10,000lbs. It worked fine down in FL but up here it just doesn't get it done.
My next truck will definitley be a diesel, and probably not a Ford diesel. Just my 2 cents.
