What 17" wheels does Ford put on stock? The Raptors are 17", but all the others I've seen are 18" or 20".
I'm not totally familiar with all Reese hitches, but does the "round bar" setup include sway control?
Another issue could be how the trailer is loaded. Some time on the scales would help:
Weigh truck solo and get front and rear axle weights. Weigh trailer solo and get total weight. Hook up with WD bars, then weigh each truck axle, and the trailer's axles. Re-weigh this setup with WD bars disconnected (this method should show 12 or so percent of trailer's total weight on the hitch).
A heavily rear-loaded trailer will wag way too much.

The OEM tires/wheels on my 2011 F-150 were
P265/70-17, I switched them out for LT tires and it did help with the shimmy but not enough.
What y'all are missing is that this isn't sway of the trailer, the trailer is tracking just fine. It is a shimmy back and forth of the tail of the truck. Think of it as if someone was pushing sideways or rocking the back of the truck rapidly.
I had people follow me while towing that reported the trailer was stable but the rear of the truck was moving.
I agree that the OP needs to make sure that his hitch is correctly adjusted but that isn't going to alleviate or even reduce this problem. I know this because we tried adjusting it out with the hitch and even tried the Equalizer hitch. It just wasn't the trailer moving.... it is the truck.
I finally solved it by replacing the truck, after spending a couple of grand trying to fix the issue.
Call it harmonics, call it a spring issue, call it a light weight truck, call it whatever but the bottom line was.... the DW was uncomfortable with the constant rocking of the truck while we towed. The truck had plenty of power, it had plenty of payload but it just wasn't up to the task.
In the truck's defense it wasn't purchased as a tow vehicle, had that been the intent it would have at the least been the HEAVY DUTY version. It was bought to haul the DW and grandkids around comfortably. We now have a truck which will do both..
