Yes, good point Pete - the Hensley Arrow is a hitch system which is installed on the trailer and plugs into a common 2" hitch receiver, while the Pull-Rite is a truck-mounted pivoting receiver which also requires components on the trailer for its operation.
Neither hitch system interchanges between vehicles well, because there is no standard coupling height. If you need a tow truck to move your Arrow-equipped trailer, be prepared to uninstall the whole thing at the roadside; similarly, the Pull-Rite system would require some hardware to come off of the trailer tongue.
The reinforces Roger's point about the tug and trailer being a combined vehicle system (okay, he didn't say it that way...).
I think if you want to tow a bunch of big trailers, you would be better off getting a good tow vehicle than adding multi-thousand-dollar mechanical marvels to any of them. Maybe even make them all goosenecks, live with having to use a pickup, and need only an ordinary fifth-wheel or ball-in-the-bed hitch.

Information is good. Lack of information is not so good, but misinformation is much worse. Check facts, and apply common sense liberally.
