I tow a trailer that weighs 350 pounds more and is a foot longer with a Nissan Titan without any issues. The Ecoboost will do the job very nicely. Get an Equalizer and you will good to go. I would recommend the longer wheelbase in the F150...If I were to buy a new truck right now, it would be an F150 ecoboost. I cannot afford a tow vehicle that's sole purpose is a TV. My truck is a daily driver. I do not want to get 12=13 mpg's that the 6.2L 250 will give when you are not towing.
