Top of the line: Propride and Hensley.....probably overkill with your setup.
Since that is a fairly long trailer (26.5') a sway control integrated with the weight distributing systems would work well for your combo: Equal-i-zer 4 pt., Reese Straight Line Dual Cam, Blue Ox Sway Pro. Fastway E2 (not quite as good as Equal-i-zer 4 pt.), and Husky Centerline (truck and trailer need to be straight when hooking up) would also work. Anderson is another option new to the market, and most users seem satisfied with that.
If you already have a WDH, then a friction sway bar would be an option, but probably not as good as a WDH with built in sway control.
If you are currently using a Reese WDH with the crooked spring bars, the dual cam can be added.
