Me too. We took a 4,000 mile trip last year and averaged 11 for the whole trip. We pull a 5,500 lb RV trailer and cruise at about 60 mph.
Question to OP. Since you have "economy" gearing (3.31s), what gear are you towing in normally? Maybe you are towing in 4th? I have 3.73s and tow in 6th 95% of the time. Just wondering if you could get better mileage by figuring out a way to go up a gear; if it will hold it. Maybe try playing with tow speed. Generally the best mileage is at 55 to 60. Over that and it really drops.
I always get my worst mileage towing "out west". The wind can be ferocious and there is no hiding from it. I've found that cross-winds are the worst both for handling and for mileage.
The worst I ever got was 8.5 into a 30 mph headwind and traveling through some significant elevation changes. Best is 13 at 60 mph on flat with a tailwind.
The Ecoboost is powerful. If you really start dipping into the boost; the fuel really disappears. The best predictor of mileage I've found is how much boost I'm using. 2 to 3 pounds is about 11 mpg. 4 to 5 lbs is around 10 mpg. I read my boost with a ScanGauge.
