Just had to add some input on the Eco-Boost fuel economy. In my Explorer, I average around 19mpg, this is on my commute which is 40 miles round trip... not deep in the city, but still plenty of lights to stop at, with some highway. All highway, like say on a roadtrip, I made it up to about 23.
In our old F-150 (2013) with the EB, the best we did was 24mpg, with a strong tailwind, driving from Rock Springs, WY, to Denver on I-80. Around town driving was probably 17-18. Down to 9-10 while towing a large toy hauler travel trailer (which I do not recommend doing with an f-150)
