Hensley Arrow: How does it REALLY work?
There have been several discussions on this hitch that have become somewhat 'controversial'. I am NOT trying to stir this controversy/bashing back up. Instead, I'd like to see a good, intelligent di...

...There have been comments in the forum regarding the weld failures of the GM receiver. I orginally assumed that the likelihood of failure would be based on tongue weight or reaction to severe bouncing of the TT. Now I wonder if a HA creates a larger moment on the weldment compared to a conventional ball hitch. The latter would have a moment arm of about 12".
Don, welcome back to the ORF. Yes, the HA will create a significantly larger yaw moment on the receiver than will a conventional hitch. You can get an ideas of how large the moment is by going back to Tim's or my force calculations. If you multiply the amount of lateral force acting at the VPP times a distance of about 47"-12"= 35" the result will approximate the amount of moment which is transferred via the HA's linkage.
...Last comment: I'm surprised that Mr. Hensley hasn't contributed to this threat.
I hope you meant "thread".
Last question: I have not read the various Hensley patents, but is there any evidence that the newer patents have led to design changes?
The latest patent deals with a means of achieving weight distribution without having to transfer the load via the HA's 4-bar linkage.

P.S. We close on our property sale tomorrow and will join the ranks of the "homeless". This likely will be my last post for a while.
