It would NOT act like a straight truck. Unfortunately, I'm not sure you can test this out with the actual hitch and that's one of the reasons I put up the video of the linkage being pivoted from both ends.
...This geometry allows the tow vehicle to change direction, collapsing one link inward to do so, and therefore the trailer turns with it.
The same geometry does not allow the travel trailer to turn the tow vehicle. The link will not collapse from the travel trailer end of the hitch. Any forces transferred through the linkage are therefore applied as a sideways force to the tow vehicle at the location of the VPP...
BTW, I appreciate how clearly and organized you made your post. I wish I could explain myself as clearly.
