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...

That's correct, the wind force does not change. But, if you increase the TT axles to pivot point distance, the TT tires will react more of the force to make up for the decreased force at the pivot point
...Further, we can assume that the wind gust exerts pressure at all points along the side of the trailer, not just at the coupler, so theoretically, there are an infinite numbers of points where force is applied, each with corresponding moments from the TT axle.
Of course, the same wind is applying its force to an infinite number of points along the same side of the TV also, so does that produce a series of counter moments?
The wind acting on the TV will produce a yaw moment acting on the TV. Most likely, the resultant wind force will act forward of the TV's rear axle producing a clockwise moment which must be countered by a left steering correction. The lateral force imposed by the TT on the TV also will produce a moment on the TV which must be countered by a steering correction. Whether the TT-imposed force acts to the right or to the left will determine the direction of this second correction.
