Have you tried loading the truck further back on the trailer ? What pressure are you running in the trailer tires. ?? Finally...towing with a dually is more stable than a single axle so you may have to just slow a little.

That was the only thing I could think of was more weight on the tongue. It looks like you have the truck forward as far as you can. If you can level it that might help.

I agree with more tongue weight and check all your tire pressures. Check the trailer suspension too, be sure everything is tight and there are no stress cracks or broken springs. If everything looks good then slow down a little.

A Reese rail kit with a gooseneck adapter leaves the ball several inches behind the location of a B and W. Too far back IMHO.

The ball should be about 5-6" in front of rear axle. It's kinda hard with a short bed but at least it should be over axle or a hair in front.

For me on the "old" truck (1996 F-350 single rear wheel 4wd) it was the flex in my rear tires walls (even when fully inflated to 80 lbs) and 15 inch D rated tires on the trailer that caused the sway. Fixed it with Michelin 10 ply on the rear of the truck and 16" 10 ply on the trailer. (it was a travel trailer, not a goose neck).
