Just as an FYI, all Ford 2012 (and up) 4x4's can be flat towed, you may have to take it to the dealer to have the "Neutral Tow" turned on via computer. The 2011's and earlier had some limits, except the Explorer & Ranger could have the Neutral Tow enabled. I work for a Ford dealer, and tow a 2003 Explorer with the neutral tow enabled. I didn't spend $300 on the neutral tow kit because all it is basically an LED that plugs in by the steering wheel, I got an LED from Radio Shack for $2.50 and haven't looked back, works like a champ.
