I had a Reese Dual cam, got a new truck and couldn't drop the tailgate down with the TT attached.
I looked for some way to move the trailer back 6" or so, the only hitch that would do it safely was the HA. I sure am glad I had to spend $2K to do it. I can now drop the tailgate and have absolutely zero sway. Unlike the dual cam that does a decent job only stopping sway after it starts, the TT can not sway with the HA.
Coming across SD, WY, and MT last fall with crosswinds gusting to 50MPH, TV and TT tracked straight down the road without any unusual steering input needed.
Try dropping a wheel of the shoulder with you Dual Cam, then try it with an HA. That will show you the difference.
