I have a 2013 F-150 4X4 Crew Cab Eco Boost with the max tow package. I tow a 24' toy hauler that I weighed and it's 7,800 pounds unloaded. My 4X4 is rated to tow 11,200 pounds. This truck pulls my toy hauler better than my 2002 F-250 4X4 crew cab V-10. It has more power than my V-10 and gets around 14 mpg around town and over 20 on the highway. Towing loaded is 8 to11 mpg. My only complaint is the tires that the truck came with from the factory 20" P-metric tires. I put a set of Michelin load range E tires on which solved the tire problem.
