Snip...It is due to the hitch point is so far back from the rear axle of the truck and the trailer is acting like a lever on the truck when the trailer is subjected to a side force.
I solved my issue with a 5th wheel, they do not sway when trucks pass due to the hitch point being over the axle.
This is exactly the reason I recommended the Hensley Hitch in my earlier post. It effectively moves the hitch point forward to just behind the axle of the tow vehicle. Therefor, the passing of trucks, gusts of wind, ruts in pavement etc. have little effect on the truck.
