Have to say when we got our trailer 3 years ago, we had our dealer "set-up" our equalizer hitch. Drove home 270+ miles with not a lot of issues until we hit the sidewinds...then it was a tail wagging the dog situation. Next trip out we had the same issue with side winds. Husband decided to start from square one with the hitch setup. Figured out that the hitch was probably never adjusted to our truck as he had to move 5 washers to set things up correctly. After that fix, we didn't have issues with sway in side winds unless it was blowing 40+. Might be something to check!
