I use a Reese dual cam for my rig and could not be happier with the performance.
My trailer is 36 feet tip to stern with a Gvw of 12000 lbs. Hitch weight fully loaded is 1470 pounds. Trailer is rock steady with absolutely no sway even in an emergency collision avoidance maneuver. Someone pulled out in front of me from a side road when I approached at 65 mph. I had to swerve immediately to avoid running over their small vehicle. The trailer followed perfectly with no sway.
I did have to stop for a change of wardrobe.
