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...

After talking with these owners, I felt that I could get much more information from the Hensley Patent Documents and from photos and videos such as the one posted by Tim showing how freely the rear unit moves relative to the front unit when not attached to a TT.
Hey Ron, speaking of vidoes, I excerpted a clip from Hensley's free DVD that shows the hitch going through it's paces hooked up to a support rig on casters. If you've seen this, sorry, but it clearly shows a guy trying to make the head translate while pushing laterally on the TT end, with absolutely no luck. But it easily does so when pulling from the TV end.
I think the problem with Tim's video is that the strut bars are not hooked up, so it's not a full test of the hitch's resistance to a lateral force.

This is a quicktime file (OK, I'm a Mac guy, and proud of it :D) and if you need the free quicktime player to watch it, you can get it here: http://www.apple.com/quicktime/download/mac.html or for windoz machines, here : http://www.apple.com/quicktime/download/win.html
It appears to me that the frame supporting the TT end of the assembly is in fact on casters, free to rotate 360 degrees (you can see them rotate more clearly toward the end of the clip) so your contention that the resistance of the TT tires to lateral forces as being the primary resistance to sway isn't the case.
Let me know what you think.
