Just a thought.....you may be able to buy the tongue from Bushtec with the heim joint already installed and incorporate it to your trailer. There is a lot to be said for those heim joints wether it's a 5 ton trailer being pulled with a 6 by (Marine Corps days) or a lightweight Bushtec being pulled by a motorcycle. Any kind of trailer would benefit from the heim joint and captured ball vs. the standard rigid ball. And.....the bonus is that you don't have the "slop" in the captured ball that you have in the standard rigid ball. 
I appreciate you insight and experience on this matter.
Even a heim joint will have limits. So in the case of the Bushtec, "IF" you went down, it would hit its limits and bind, correct?
Do you have any close up pics of the Bushtec heim joint attached and un-attached? Just curious.
With the Bushtec heim joint hitch, do you have to use wrenches to connect/disconnect the trailer?
Again, being a newbe to trailers, I greatly appreciate letting me ask some probably common knowledge questions. I look forward to using it on the way to ES.
Just one last question, I've been told that tongue weight is in the 50 to 60 lbs range. Is this a good rule of thumb? More? Less?
Thanks again...
