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...

--- If the benefit of the HA is marginal with most of the resistive work being done by the TT tires, why does the HA provide such great improvement over a TT with a standard hitch? After all, it's got the same tires.....Tim's calcs seem to be more in ballpark from an expected magnitude.
With apologies to all who have seen the following too many times, my answer to Don's question is highlighted in red:
The HA does not "lock up".
The HA does not prevent the trailer from swinging.
Lateral forces on the TT's tires control the swinging.
The HA works by reducing the magnitude of lateral force and by moving the effective point of application closer to the TV's rear axle. This significantly reduces the ability of the TT to "steer" the TV.
This, alone, is sufficient to explain the HA's anti-sway capabilities.
A standard hitch does not reduce the ability of the TT to steer the TV. The HA does.
