Change last two letters in Anderson to "en" (Andersen) and do a search. There have been numerous threads on it.
I have one, but, prefer using my BlueOx Swaypro. I keep the Andersen for a backup.
BlueOx has built in sway control and I find it faster to hitch up, than the Andersen. BlueOx is also better with restoring lost weight on your front axle. The primary purpose of a weight distributing hitch. They're not far apart on price.
