I have the same tt and towed it with a 2014 and my current 18 f150. I have had zero issues tow in the mountains out west or the winds in getting there.

I just purchased a slx 8 284bhs. I have an 18 f150 supercrew with the 3.5 ecoboost and standard tow package. I haven't pulled it yet as they are still preparing it at the dealer. I'm hoping my luck is as good as you all have had, fingers crossed I'm nervous.
