I think my truck (2023 F150) pulls my trailer great, but I do get noticeable sway when a semi passes, or cross winds. I’ve looked at anti sway devices that use the trailer brakes, and rear axle bars. I have a Blue Ox weight distribution hitch.

I”ve read conflicting things about them, but I’m still leaning toward a rear axle sway bar.

For those who have done the upgrade, I’d be interested in your experience.
 
Sway bars, or high-tech solutions are for the most part helpful. But they can be considered bandaids, or security blankets, for a more pressing issue!

The most prudent method for sway control while trucks pass are completely in the users willingness to stay off the road when facing side winds, or heading into headwinds or tailwinds.

What you face is a wind dam the trucker is dealing with.

It is most dangerous with an improperly loaded trailer, and nothing can correct that kind of stupid.
 
I put a rear sway bar on my truck and it definitely made it more stable when cornering. I can't speak to the sway from air currents when towing as I put it on before I bought my trailer.
