As to longevity...there are 30 year old Dual Cam sway controls out there still doing their thing. The Reese trunnion system is very good and serviceable. Not sure If you have trunnion or round bar though. For the Reese hitches I really prefer the Trunnion style for DC.
You can replace the trunnion ends on the bars if they wear out and a new hitch head is about $140 ish on Etrailer if the hitch head fails.
The only other WD hitch that would meet your specs is the BlueOx Sway Pro...the Hensleys (Arrow, and ProPride) are not what I would consider super easy to hook up but they are not super hard either. I
Once the Reese Dual Cam is set up correctly its one of easiest hitches to hook up. IMHO...if it's working for you then run it.
Thanks!
