With mine and no trailer, if I can make myself cruise along at 65 MPH, it gets about 20 MPG. But hang on a TT or enclosed trailer of any weight from empty to 7,000 pounds gross trailer weight and MPG drops to 10 MPG if no headwind or hills, or 8 to 9 MPG with a headwind or hill country.
But who wants to poke along at 65 with no trailer when the ticket limit is 79? So I usually lock the cruise on 78 or 79 and get 14 to 15 MPG per the lie-o-meter.
That's with an Ecoboost? Man I'm glad I didn't fall for the hype. 2009 5.4 3:55 gears straight cab long bed. Cruise set at 80 17 mpg all day long, even my 2000 with 3:73 gears would do the same thing. That is hand figured, not the lie-o-meter.
