Acdii, The difference in body weight isn't that significant for that trailer and it's unlikely that Ford did anything to the suspension to induce sway. The solution likely lies in an appropriate sized and properly set up ideally per scales WDH.
Certainly you are unlikely over on combined axles or CVWR. So it's just in the setup. YouTube has some good videos on how to properly set up a WDH. Also your hitch mfg should have instructions for setting up your hitch even if you bought it 2nd hand.
You would think not but the one individual I was following had a similar size and weight trailer was having the exact issue. He tried air bags, sway bar, shocks, tires and even replaced the hitch but still had a poor handling truck. This one situation stands out because this individual is a very experienced and knowledgeable, the last I heard he was likely going back to a F250. He also had an issue with the backend kicking sideways when hitting bumps unloaded, the dealers involved say the truck is working as designed.
