To the OP,
1. There are WD hitches out there that distribute the weight between the trailer and TV. They level things out and return weight back to the front end of the TV.
2. A WD hitch by itself does not reduce sway. The first level to help this is the add on friction sway bar.
3. Today there are hitches that combine WD with Sway control at the same time. Andersons, Equalizer Brand and Reese hitches are examples of this.
4. The Hensley or Pro Pride are different, have an entirely different design and suggest that you will never have to worry about sway....ever. People who own these are high on them but this thread is the first time that I have heard an owner actually claim that aside from all the miraculous claims, they will increase MPG too! Wow!
I have been towing for over 20 years now and have ONLY used an Equalizer. Back in the day I had to get a hitch, I was looking for a quick and easy set up. I did not like any of the spring up chain type hitches for they were problematic when backing up. You had to disengage these before backing into your spot upon arriving. This has changed and is no longer an issue. The Hensley is heavy, and you have to back the truck into the stinger. Most owners say this is not an issue after you have sufficient experience and I will accept that. I only knew that after watching two different owners struggle with hooking up in a camp that was a bit off level, I decided that this was not for me.
I went with the Equalizer and have yet to experience any issues. If I did have trouble with WD or sway episodes I would look at a different hitch. But since I now have over 50K miles towing my current trailer without any issues, I am not in a hurry to get something "new". That and the cost of a new Henlsey keeps me happy with my setup. Hensley is a very good hitch, not question. The best? Perhaps, but.....is the extreme cost a justification to drop a hitch that works for me?
