He may have simply needed a lot more tongue weight. Depending on the size trailer a WDH may not be needed.
On these boards a WDH is an absolute requirement and if you dont use one, it will open the gates of hell and satan will kick off the apocalypse LOL.
In the real world not so much. I know plenty of people towing travel and other types of trailers without WD with heavy duty trucks, and no ill effects including no sway in any way shape or form. Try putting a WDH on a 26' or 28' boxed equipment trailer loaded down with construction equipment that you've connected to the truck with a pintle hitch.
