I haven't had any issues. I do have the Ford brake controller installed since it integrates with the emergency braking system and will apply the trailer brakes. You can feel the wind, but nothing I couldn't handle. I did find I needed to disable the Ford sway control, as it was fighting...
I opted to go with a shorter trailer. My trailer is 23' 11" from bumper to hitch. It is a Rockwood MiniLite 2205s. Rockwood Mini Lite 2205S | Forest River RV - Manufacturer of Travel Trailers - Fifth Wheels - Tent Campers - Motorhomes (forestriverinc.com)
The Ranger handles this trailer...
I had one of those piece of crap dual clutch transmission Focus I bought in 2016 new. Finally got Ford to buy that thing back! Now I'm happily driving a Ranger and have no issues whatsoever with its transmission.
