Same issue, adaptive cruise without lane centering while towing everything is solide and no sway.
With lane centering and 27 foot RV it is constantly adjusting. Not enough to cause concern but
those constant small adjustments does cause tire scuffing.
I've had my F-150 Powerboost 4 weeks and had not noticed bur maybe because of volume of
sound system. First noticed when turned volume down with friends in truck. Was very concerned
until reading these post. Do plan to have it investigated by Ford Dealer.
