How about you toss 13% out the window? Your assumptions are muddying the discussion. And going 70 mph, wow, that sure is wild.(eyes rolling....) I imagine i would have found out the hard way with nearly 20000 miles on the tires, always going 70. Same with the truck.
Tongue weight can be managed, at 11.5% from the OEM, keeping that around there can yield a safe, nice towing combo. End of story.
And todays F150 is a different truck than even 5 years ago, it's no miracle truck, but it is fine at 100% GVWR.
One obviously does not shoot for 13% tongue weight, just because you day so, if it overloads their truck. I should not have to even post that.

To the OP, can you weigh it? Tweak the WDH to get your axle weights under and see what is what. Your setup can be managed to be legal and safe based on tongue weight, passenger load, and WDH settings. Only you can decide if it tows to your satisfaction and works for you.

As I often note...opinions and YMMV, alas facts do not. You did not address my question, ST tires? which are rated for a max of 65 mph and found on most TT's. Towing a TT without a WDH in the mountains at 70 (OK boys and girls what is wrong with this picture?). Nothing wrong with running at any trucks GVWR, it is not ideal but certainly can be done but the OP's numbers put him hundreds of pounds over GVWR which is neither safe, smart or legal. Sounds like you may have been there but details on your rig are glaringly absent.

Now we do agree on a trip to the scales, not just for the OP but for all of us....been there done that a couple of times.

With a 30'+ TT, especially one pulled by a half ton, anything less than 13% TW IS a potential sway problem, sorry if that upsets you but facts are like that sometimes. If 13% TW overloads the truck you do not have enough truck. Exceeding your RAWR not only is a very bad idea but voids your warranty (but then I should not have to post that). :R
