 Absolutely the worst fuel economy of any truck I have ever owned! I only get 7 miles per gallon towing a utility trailer Ford should be embarrassed. Ford's response to me when I questioned the gas mileage was they are not responsible for mileage. You bought it, you own it, as long as it meets "factory specs" it's my problem. $48,000 truck and I get 12 MPG daily and 7 MPG towing and Ford says there is nothing wrong. I will unload this thing ASAP and never buy another Ford. The fuel tank is not only smaller than my 2005 F250 but at 7 MPG my effective range is about 125-150 miles..wow doesn't that make travel fun
