And that's your opinion. A WDH . . . prevents sway. A TT that has a properly setup WDH will not sway, even without sway control. Sway control is only for those emergency events when you induce sway by dodging a road hazard, or accident. Sway control is not needed in normal driving.
However. A driver must take the time to setup the WDH properly.
This is not true. (I omitted the part that IS true, about returning weight to the steering axle.) Sway in a trailer is an oscillation of the trailer about the tow ball. It is dependent totally on the trailer's balance and vehicle speed. A WDH that has no sway control built in has absolutely no effect on trailer sway.
Now, a WDH may, and only may, help the tow vehicle resist the sway of the trailer, making it easier for you to maintain control, but it does nothing to prevent or stop the trailer from swaying. Again, if the WDH does not have sway control built in.
