Do I need wt distribution and/or anti-sway bars?

I just purchased a 2019 Ford Expedition (4x4 and 3.73 axle ratio, which can tow 9000lbs and also has the heavy duty tow pkg) and am towing a 25 foot Rockwood Roo, which weighs about 6500 pounds. I used weight distribution bars with my previous tow vehicle. Will I need it with the Expedition?
Also, the Expedition has trailer sway control, will I still need the anti-sway bar installed?
Thanks, Lori
