Last time I towed my 32' travel trailer, it was in strong head winds. The Ford anti-sway actually did engage once. It caught me by surprise as the dash screen switched to an orange screen which read "anti-sway engaged" or something to that effect. The truck noticeably slowed as the brakes were engaged. I use a WD hitch also, but the winds were really knocking me all over the road. Its good to know that I have that extra level of help when mother nature's in a bad mood.
