I agree, they need more tongue weight, better adjustment on the WDH or more than likely, a WDH with built in sway control. If they want to completely eliminate sway...have them buy a ProPride hitch.

You should have no problems getting to 100% FALR restoration with the equalizer. I had it on my F150 with no issue at all, and it could have done more. Mine does make noise when doing tight turns, but there are some plastic bushings you can get to quiet that down (I have not).
