If the Ford system is anything like what I had on my Tundra, it is reactive, and doesn't do anything until a sway event has already started.
My suggestion is to use your current sway-bar setup as it's proactive in trying to prevent a sway event from happening in the first place. The trucks system is a worst-case scenario back-up
