I just want to clear the air on some of the misconceptions this thread is generating.
1. Regarding the assuption that the brackets can slide on the frame: that's a WAG at best. In 3000 miles towing cross-country the Andersen setpoints haven't moved at all - none, nada, ziltch. I simply followed the intall instructions and the attachment is rock solid. The belt and suspender guys can certainly through-bolt the brackets for an added sense of security.
2. Regarding the pressure on the hitch latch mechanism, I can see the wear marks on the ball clearly. They are from the hemisphical hitch socket dome, not the latch. The only time the latch is touching the ball is when I lift the tongue up high to set the chain tension. This is exactly the same as on my old traditional WD hitch.
3. Folks who envision the ball slamming around inside the hitch socket are far from the mark. The ball is firmly clamped into the dome of the hitch. There is no slop in this connection.
Only time and experience will measure if this new hitch has merit. The uninformed WAG game has run a bit far in this thread.
