I did find an interesting reference. http://caravanandmotorhomebooks.com/caravan-dynamics/
They put the roll center just about ground level.

This has been interesting reading all the comments and posts of g, y or whatever forces are in some tests by whoever to show shock dampening from some folks. I know that you all realize that you can find statistics to prove anything you want. If you're an engineer in the field I can understand your comments and stats, that's how your mind works. But, and I'm sure I'll take some hits for this. I think most of the molded trailer crowd here is old enough to remember when our cars/trucks had just plain shocks. No electronic gismos and controls. Remember when the shocks wore out and the car bounced down the road for a while after a dip or bump? Wonder what that would look like on a graph in comparison? Bottom line, adding shocks to a trailer really looks like it helps and it certainly can't hurt the ride. There have been a few members that have added them and are very happy with the results. Guess I'm old school, I can look at graphs but I'll always take real world user experiences first.

Interesting mention of roll center since the coupling between the trailer and TV and their roll centers have a large effect on the stability of the total system.
On my VW station wagon the IRS has a pretty low roll center and negative camber. It also has a rear anti-roll bar standard. With the stiffer, more highly damped rear end the trailer -TV combination works quite well and as to stability if you sharply displace the steering wheel the combination reacts and also damps out ant oscillation very quickly!
I am currently rebuilding the '86 Scamp 16 footer and changing the axle for one that has some suspension travel left. I have chosen the Flexiride since I can change the ride height ans since I had to buy new wheels anyway (no 4 lug hubs with brakes available) I went to 14" wheels and 205 75 14 tires which are taller and therefore have (perhaps) more sidewall.
I am working to keep the CG low and the trailer balanced as I build to retain as much or the good handling as possible.
I would like to have shocks for this setup. but I don't think that the orbital system will fit. As a result I am looking into importing a set of the AL-KO octagon shocks and welding the necessary brackets to the trailing arms.

Since AL-KO is the originator of the rubber suspended torsion shock I assume that they know a little about whether or not they need additional damping!

In the end, we do this for the pleasure of it and we should each do what is the most satisfying. As with most complex systems the answers are never clear cut, situations vary and personal preference varies.

Sounds like an interesting and fun project. Keep us updated with any progress.
