I have decided that Chuck wins the prize on this issue.
Enjoy the popcorn.
BTW, who is Jerry? Anyone? Anyone?
Below is the same picture found earlier in this thread which was the basis of my original question:
The thumbnail below is of the same 550 pound spring bars mounted on an adjustable drawbar. Per Reese's instructions, the bars are are now basically parallel to the frame. If you look closely at the spring bar's cam follower, you will notice that it now sits in a better orientation than it did in the picture above.
The anti-sway characteristics of the setup below were the best they have ever been since I have owned the Airstream. This confused me since, although my original 1000 pound bars were too stiff for my 3/4 ton tow vehicle, they did distribute weight on the dual cams. The mystery was finally solved earlier this week when I noticed that one of my original bars is a half inch longer
than the other one.
Since the bars are supposed to be interchangeable, this would make a difference if the bars were mixed up. Sure enough, after examining wear patterns on the cams & followers, that is exactly what had occurred.
The lighter weight bars also made a remarkable
difference in the way the Airstream towed. This last trip was the "cushiest" ride my Suburban has ever had while towing my Overlander. I'm sure the rivets on the Airstream's front plate appreciated the change too.
Any fears about the spring bars popping off the cams were laid to rest during two separate manuevers, on left handed & one right handed, when I had to come about hard (in slow speed) to change course. There's a funny story attached to my changing course, but I'll spare you, and just say thanks to everyone who contributed to this thread.
