I tried a trail air hitch, both the TS3 and the TS2, neither helped the bouncing of the truck, in fact the truck bounced worse with the two hitches than with a regular solid 20k Reese hitch, to the point of being uncontrollable. I ended up reducing the spring effect of the truck to get the best ride by removing the snubbers on the front of the overloads, and set the rear tires at 65 lbs air pressure as well as putting the most pin weight on the truck as possible. This is with a 2011 3500 dually with 3000 lbs pin weight and 15,500 trailer weight.
