Just signed up and read the whole thread so far. I have a 14 Lariat SuperCrew 4x4 EB. Last July I bought it with around 40,000 miles. I traded in an 07 SC 4x4 with the 5.4 and 260,000 miles. Since the 07 was new, I towed a 9,000 lb 32' 5th wheel. All up it was probably closer to 10,000 lbs....with a 17-1/2' Zodiac (military inflatable) boat behind it, maybe closer to 11,000lbs. Before anyone hijacks this thread with your advice about that, save it, that's not the subject. I got 230,000 miles out of the transmission towing that 5th wheel all over the country, even through the Rockies and all over the Southwest. Motor never ran hot. The gauge never moved.
Now to the 14 EB. First noticed the heating problem going out of Phx up to Lake Powell towing my 28 foot boat that's probably around 6,000 lbs. Heated up quickly but dropped quickly when I got to the top. However, the a/c kicked off. But returned upon the gauge going down. Then in October, I towed that 5th wheel PLUS my UTV on a 13' trailer (around 2300 added pounds) to Utah to go deer hunting. The EB tows like a beast but the overheating is a huge concern. It only does in on long, steep hills like going north out of Phx or I-8 east in the mountains out San Diego. If you watch the EB torture test on Youtube, they never mention any of this in their hill climb towing races they did against Chevy and Dodge. I had my thermostat replaced and cooling system flushed and it still does it. Considering the full Race radiator now. But I see it doesn't help much. I'm interested to hear some more details on that.

have you tried runing up hills in 4th or 5th gear ( lock out 5 and or 6th) and let the engine do more work and take a lil load off the turbos??

Kinda starts making sense that guys going to the full-race radiator aren't having their problems fixed as the airflow is choked by the electric fans. You can make the radiator huge, but without enough airflow it still won't keep up.
Unfortunately no easy way to check that theory. Would be a TON of work to try and retrofit a fan in an ecoboost.
Interesting, the new F150 diesel is going to use a mechanical fan.
