I would run your Dual Cam without the cams. Just remove the cams and install the chains to the bars like a standard WD hitch.
On the built in sway control in the truck. I can tell you they work as designed! And is amazing! My wife's 13 Explorer has it built in and when towing my snowmobiles to northern WI (3 place trailer) a couple times it got a bit loose on some ice covered highway. You could feel and see the trailer start swaying, then you could feel the car brakes counteract it and stop the trailer sway. Very awesome system!
