If you're seriously considering an Anderson WDH, google Anderson hitches and add "review." The Airstream guys were discussing some issues they were having with the Anderson. Several guys were having the latch that locks around the ball coming undone. On a norma WDH, the spring bars tend to pull the A-frame of the hitch DOWN. On the Anderson, the springs/chains try to pull the A-frame towards the ball, which is apparently causing some to try to unlatch. There are other concerns regarding the brackets on the A-frame. Again, on a normal WDH, the srping bars are pulling down, but on the Anderson, the springs/chains are trying to pull the brackets forward. If they were to slide, you'd have an issue. There's apparently a "set screw" that's supposed to keep them from sliding, but they were questioning its adequacy. I do like the no-grease, though!
