The eco boost is a great engine BUT it is either Eco or Boost! I had it in my last 2 F150s and in the last one when I traded, it was showing an average of just over 15mpg on on the lie-o-meter over its life. Of course I am fairly heavy on the RH pedal and living at 6500 and traveling up and over Mt rose (10k') regularly impacts that. Best I saw on long runs was 18-19.Interesting comment. The 3.5-liter ecoboost engine I'm looking at first came out in 2009 IIRC.
I'm more concerned about the "busy" behavior of a 10-speed automatic, although the tight gear spacing will be great for towing.
My new F150 PS has the 10 speed and I am very impressed with it. Doesn't feel busy at all, very smooth and pretty seamless behavior. It is programmed to skip gears on a lot of occasions particularly moving up the box. Certainly makes a very good combo with the Diesel and I dont feel like I am down a lot on power compared to the Eco.
