I have a 2015 F150 with the 3.5 eco-boost and it has been a good one.
I have towed my tractor with disk,it is a 175 Massy/with calcium in the rear tires with out any problems.
After hauling 2 trailer loads of household goods from Waco to Lubbock the only thing i could say is i wished the millage was a tad better but with the gas we get around here it's not bad for the load.
It got 10-11 mpg on the return trip in tow mode.
I grew up just a few miles west of Plains and live NW of Waco a little today. I go to Lubbock area a few times a year. After 20 plus years and multiple vehicles, I generally find I get 3-5 mpg better mileage going east than going west on that trip but not all ways if I end up in a strong head wind. I attribute the mileage difference to predominate westerly winds and gaining altitude most of the way on the Westbound route.
