I gotta ask, mileage towing that monster? I have heard good things about the Ecoboost's towing ability and power, but horror stories about fuel economy when towing, due to constantly having to be in the boost. Like the 10-15 people I have talked to have never reported more than 7 mpg (max), usually around 5 mpg when towing heavy loads. Yours? I can't imagine you will be getting much more than 5-6 towing 7% grades with that large trailer.
