Thank you APT. Your comments were very helpful, as was the extra reading. That was exactly what I was looking for.
I gather from the additional text that tilting the ball back with the same number of links and the bars parallel, can increase the weight transfer forward to the front of the truck. I never thought of that. Did I get that right?
Now another question: Adjusting the friction sway control seems to be very subjective. How does one know when he has too much friction? Are there any suggestions how to get it close to begin with, avoiding numerous trail and error stops? I see people posting they pull TTs all the time and have no sway. I'm not there yet.
Again Thank you.
