You just about have it. The only thing missing is that there are sway controls that can be turned off and allow you to retain weight distribution. Those are the friction sway control arms that are added on to a standard weight distribution hitch that are made by just about everyone.
That really only matters if you may be towing in slick conditions such as dirt roads, gravel roads, or icy roads. It is pretty nice to be able to retain weight distribution and have the option to remove the sway control.
Thanks!
