I never knew this forum existed. I'm glad I found it. I purchased a 2012 F150 SuperCrew last November. It has the 3.5L EcoBoost, 3.55 rear end, Platinum Package, tailgate step and box extender. The truck drives great but the gas mileage sucks huge. I'm not a "foot-in-the-carburetor" type guy but I have never seen 20 MPG at any speed come up on my dash. I have about 8800 miles on it now and if I knew then what I am experiencing now, I would never have bought this truck. I do not claim to know everything about this truck, however, I feel the mileage should be better. Maybe there is something that someone here knows of that could help me to better understand this truck and its performance. On a side note, this past weekend I was pulling my Bobcat (on a trailer) and the dash continuously switched back and forth from trailer connected to trailer disconnected...any ideas?
