Bob, have you induced a sway in your trailer to test it?
Just curious, but I assume your Reese "HP" Dual Cam is the 2nd version "HP" based on your JOF thread referenced below.
In the latest Reese instructions REV "K" & "L" they do recommend the incorporation of a screw (at the snap-up bracket) on Jayco frames, and I contacted both Reese and Jayco on this added screw but neither gave me a clear explanation "why". In the past bolting (or screw) was recommended by Reese in cases of a heavy tongue loads (1,200lbs plus) on the standard WDH's (no Dual Cam) because the snap-up chain "moved" during TV turns which in some cases could move the snap-up bracket as well.
As far as the round spring bars parallel with the TT frame is ideal, but a "slight" downward angle is fine especially if it provides for better component clearances. The trunnion style spring bars can be set at a more aggressive downward angle do to the associated ball mount style.
I haven't induced sway, but have had a couple of driving conditions over the years (sudden strong crosswind, etc.) that I could "feel" the Dual Cam working at keeping the TV and TT traveling in a straight line.
If you get a chance, post some pics of your finished installation in your thread
. Would be a great visual aid for others installing their own Reese HP Dual Cam.
