There is a Camco elite EQ hitch sold at CW.
Its alot like the round bar Reese Pro series.
Check the TW ... depending on the TW of your TT, you may or may not really need the WDH. If set up correctly, i don't think it will hurt you to use it.
Take the time to do the following and I think your sway issue will be solved.
IF CW set up your hitch for you, then that might not have been done correctly. ( common occurrence )
I would google the youtube for setting up the Pro Series hitch or use
David's hitch set up.Having enough TW is the most common cause of trailer sway. Go to a scale and properly weigh the combo. Truck alone-then with WDH - then w/o WDH.

Tire PSI , max the TT and TV PSI .
Hitch set up , learn how to properly set up the hitch. Take measurements of wheel well height, Make sure the TT frame is level to the ground when you redo your hitch set up.
