The problem isn't so much the turbo's, it's the direct injection and the resulting carbon build up at higher mileage.
Fords fix in the past has been to replace the heads.
And it's not a "Ford" thing; any gas vehicle with DI is subject to this problem. That's not a reason to not tow with it though.
Now someone is going to come on and say they have 3 million miles and never heard of this or that I'm some sort of anti Ford guy. My history of posts proves otherwise and besides, I owned lots of Ford and Chevys.
I suggest you do some internet research for yourself.
