11 EcoBoost here also, and the only way that I can see 20 mpg is to really feather the throttle, no cruise control and stay around 55 mph. Normal driving on highway with cruise is 17-18 mpg, FX4 screw 3.73. Also, the braking in the tow/haul mode is accomplished by the transmission. Great truck, we averaged 12.4 mpg on our current trip of 500 miles, mostly 60-65 mph with cruise, with little to no wind.

I'm pretty sure most of the Ecoboost drivers doing a lot of 20+mpg on the highway (and keeping up with the traffic) are running the 3.31 diff with 2wd... TANSTAAFL after all.

2012 Eco Boost
Don't know about all the technical stuff. But, we pulled a Safari all over with a 2012 F150 Eco Boost cab1/2 and got around 17 mpg. We also pulled our 30' Sovereign and got around 14 mpg. with plenty of power. So much better then our 250.

A little unclear as to why tongue weight subtracts from the payload?

Because the tongue weight is being carried by the truck in essentially the same way as if you put a weight equal to the tongue weight in the cargo bed.
Now, when you're using weight distribution, which axle is carrying how much weight varies based on the tension of the weight distribution equipment, but you are always going to be adding to the weight the truck's axles are carrying when you put a properly-set-up trailer on the ball.

Did some more homework and your post above makes sense. Now I get it. I don't think it is a major issue at this point but adding the weight to the TV does limit the payload. A little concerned about that. It does not appear that I have a lot of room to spare. Love the truck (2013 Echo Boost) but should have done a little more investigation about the payload factor.

You might also consider a set of Firestone Air Bags with in-cab compressor on your F-150. Like was said above, the C or P rated tires are a PITA and for towing, I much prefer an 17 or 18" with D or E rated tires. In addition, if your AS has ST tires, think about switching to LT's. Read the thousands of posts on that subject.
