John,
My last HD Cummins was the same truck (05)
I have used Reese Dual cam, Husky Brute, and Equalizer in past and they all do a good job but some noisy especially when backing up.
The tech (4 years ago) suggested the Blue Ox Sway Pro and I continue to use it today on my Lance TT. Love it for built in sway control, no loose parts, always clean (powder coated) sealed grease certs, and the easiest to hook up with the 'new roller cam' design.
The Blue Ox has worked perfectly. The Hensley and Pro Pride are great systems but expensive.
I have used Prodigy P2 for many years (now have built in controller on my new truck) and perform very good.
