First question, what is the tire pressure on the front tires? If it is 80psi, the max on the tire sidewall for the maximum load capacity, it is way to much. Look at the Ford sticker on the inside of the drivers door jamb and it will say the pressure for the front will be 65psi, the amount needed for the maximum load if the axle is loaded to the maximum gross axle rating. When my front pressure was set to 80, the vehicle was almost impossible to handle, when I dropped it down to 65, it became a pleasure to drive.
Note all tire pressures are cold ambient pressure, whether it be 65 in 0F or 65 in 90F ,
Second, sway when flat towing. I had a similar problem when I started flat towing the CRV. The problem was a sloppy hitch receiver on the MH. It allowed a side to side movement in the tow bar. An 1/8” at the MH would almost be 2” at the front wheels of the toad. I use a hitch quiet?sp , to make the connection solid. In my case, that reduced/eliminated the sway.
