I think that is decent mileage for a 4x4 towing a TM. My mileage without towing averages 17.4 mpg on flat Socal roads with 80% highway and 20% stop & go city. Again that is a lot better numbers that I got out of my '03 F150 w/ the 5.4L v8.
I agree that those are excellent towing mpg numbers! I could live with those, but I've read on other forums from Ecoboost owners that they are getting around 9 mpg while towing. I couldn't live with that. I'm guessing that I have a heavier total load (3124KS versus 2720) than you, which will effect overall mpg, but I drive about the same speed, which is also a major contributor to mpg, especially while towing.

My truck is primarily a tow vehicle (it is the third vehicle in a two person family), so non-towing mpg aren't as important to me.

Maybe some of the other Ecoboost TM members will join in with their experiences in towing mpg?
