The higher octane rating is only used if the engine is timed for it (or the computer can adjust the timing on the fly for it). If the engine calls for 87, don't bother with 93 because it'd just be a waste of money.

I have the 7 year 100,000 mile bumper to bumper warranty.

I have 18,000 miles on the truck. Dealer said after several key turns code gets erased.

As mentioned you can have anyone (parts stores) scan for codes, not just the dealership. I would go pull the hill and have it scanned asap.
I doubt the dealership would check the thermostat, coolant level probably. You can buy a coolant tester and see what the % is at.
Premium fuel is recommended for towing. More octane = more power which makes your motor work not as hard.
What speed are you trying to tow at? Are you in Drive or tow haul mode?

Thermostat won't help, from previous discussions about this, the real fix is a much larger intercooler. The ford factory one is not large enough in situations like yours. To make the engine build less heat you can try to let the engine Rev more, the truck will want to maintain speed by building boost, this builds heat. Try bringing your RPMs up a bit which may help.
This is one reason I like the 5.0 when towing my GN, it has more coolant capacity, and more oil capacity than the eco, both of which help it shed heat when working hard. It also has no turbos adding heat. I have pulled my GN up 6% grades in close to 100 degree heat with high humidity for 2 to 3 miles and the temp was rock steady, and my towed weight is a close to 8k.

“Regular” unleaded gasoline with a pump (R+M)/2 octane rating of 87 is
recommended. Some stations offer fuels posted as “Regular” with an
octane rating below 87, particularly in high altitude areas. Fuels with
octane levels below 87 are not recommended. Premium fuel will provide
improved performance and is recommended for severe duty usage such
as trailer tow.
You should be using Premium fuel while towing...
Look at your intercooler. Do you have any black plastic blocker plates installed over the front of it?

I forgot to ask but have you checked for any blockage in your radiator? Dirt, debris, etc?
Have you tried washing it out with a hose?

Hot weather towing and I definitely notice a power increase when switching to 91 from 87. Much crisper performance and power.
Colder weather not so much. Most of my trailer towing gets 91 in the tank now, especially since I'm tuned.
I can get my temperature up towing my 8000# trailer up long steep grades. I simply lift my foot back to 1/2 or 1/3 throttle and watch the temperature drop. Still pull good speeds too, just drop 10 mph or so.
I would try a 180 thermostat if you are an Arizona resident. No need for my northern Canadian 195. Your thermostat may not be opening as fully as you need and a new one is a cheap way to investigate that.
After that only more radiator and coolant will help.
I use the torque pro app on my phone while towing and set up alarms to warn me when I get too power happy up long hills and the temps soar. Early warning helps me back off early enough to maintain an aggressive paced but hold temperatures.
