Tow vehicle is an F350 Diesel, AS 34 Classic. Have posted on this before, but as delivered the stability was very dodgy, with a fair amount of wiggle in crosswind gusts especially. Increasing the weight distribution by 1 link helped but didn't cure the issue.
Got some good advice from SteveH and others to adjust the sway control arms. The saddle on one side was clearly not seated on the cam after a straight ahead pull. After several attempts at "the official procedure": loosen the sway arm clamps, pull ahead, stop with trailer brakes only, then clamp things down tight, I was not able to get things to budge on their own.
Solution, a bit inelegant, was to loosen the clamps and whack the sway arm pivot into place with a good-sized ball peen hammer. It's pretty easy to tell when you have it correctly located. Clamped it back down, and away we went.
This completely changed the towing character of our rig. Was white knuckle, now it is one finger on the wheel stable. We are just finishing up a 4000 mile trip thru the Canadian Maritime provinces, under every wind condition, and the combo was always very stable. My wife does half the towing now, and she would not before.
My conclusion, the adjustment of the DC hitch matters a lot, but it is not as tricky and fiddly as I thought it would be. Just mark the bars left and right, adjust the system so the cams are fully seated in the straight ahead position, get the right weight distribution, and things should be good.
I know that there are a lot of opinions on this topic...just adding my story and good outcome.
