Upodate: the truck came back from the dealership as "nothing's wrong with it as far as we can tell. The faults cleared, so there's nothing we can do." Nonetheless, both the shop foreman and the service manager drove the truck with the Open Range hooked up, and both thought the truck was the trailer's "b!tch." In fact, the shop foreman said "I wouldn't pull it to Lake Arrowhead (a 20-mile trip)." The engineers never gave them a lead or any information to go on.
I just put new 275/70/18 LT Load Range E 12-ply tires on it, as well as new Bilstein 5100 rear shocks. On a 220-mile round trip this weekend, it was better. Still not as good as my '10 Silverado. The F150 has a LOT more side-to-side push with cross-winds. Granted, I had put air bags and LT tires on the Silverado, which I had never expected to have to do with the new F150 because of the 2,500 pound increase in towing capacity and also the increased (factory) payload capacity rating over the Silverado.
I've already plopped down $200 on Timbrens, $150 on shocks, and $500 on tires (net after selling my old tires online). I'm currently trying to decide now whether to go with a Hellwig sway bar or take the Timbrens off and go with air bags.
In addition, I KNOW that something is not right with the truck. For the first 20-30 miles today driving home, the steering wheel was cocked about 15 degrees to the left. I then went through a cloverleaf exchange and after that it was perfectly straight for the remainder of the trip. I've found a few threads online and bits of information that seem to indicate that it may be something in the EPAS (power steering - which is related to the error codes it threw on the first trip) that's causing all the problems.
Stay tuned...

Didn't remember reading his TT was that heavy but Agreed a 9k TT is more than you tow with a halfer. Even though my experience doing it was good. I believe SAE J2807 does take into account wind to some degree. But is that 9k any worse than an 8k 3500 rated for and towing a 30,000 pound load.
In a way, yes it is worse.
I've towed a lot of different trailers a lot of miles over the last 30 years. High profile trailers are the worst.
So let's take that 1/2 ton truck at 6k lbs and his long 9000 lb travel trailer...put a 30 mph crosswind against it...it's going to get pushed. The WD hitch and sway control are going to kick in and the whole setup moves away from the wind into the next lane.
Same length and profile trailer that weighs 20k behind a one ton truck weighing 9k gets hit with the same 30mph crosswind....same hitch and sway control kick in and the whole setup moves away from the wind into the next lane...A LOT SLOWER....WHY?
WEIGHT.
It has nothing to do with frame thickness, payload capacity, or what brand of shocks you put on. In those crosswind situations, weight is your friend.
It simply takes more wind to force the heavier vehicle over at the same rate as the lighter vehicle all other parameters being equal.

You didn't buy one with the HDPP; even though you were going to be towing almost 10,000 lbs. Somehow that's the engineer's fault?
Thanks, JIMNLIN for the information from the Ford Fleet Guide.
Based on that information, I should have the frame that is 0.1 inches thick. I say that because the GVWR on my truck is 7,000 pounds and the GCWR is 17,000 pounds. Trucks with the lower GVWR (I think it is 6,300 pounds) would have the 0.087 frame thickness.
We'll see what the Ford engineers say about this situation... let's just say that my case has "escalated."
You been on here long enough to know it's the payload that matters.
