Now real world from Sunday. 2013 Ecoboost f150 with hj61 on a trailer. I saw 13mpg with an average speed of 65-70mph driving 100 miles with the Land Cruiser loaded5.0 will usually get better real-world fuel economy than the Ecoboost. I've had both for rentals and frankly dislike the Ecoboost but really like the 5.0. On the pre-aluminum trucks, I could get 20 mpg highway pretty easily with the 5.0. I camped next to another TrailManor owner, who had a 2.7 Ecoboost as his tow rig and claimed 17 mpg towing at 65 mph, which seemed far-fetched to me, but who knows.
