Big time agree with that post. When I left the dealership with my setup, the dealer had only put back 60 lbs. of my "lost" 300 lbs on my steer axle. The dealers are notorious for not taking their time with the setups. I also had to move the cam brackets further back then what they had dealership had done.
The get the best possible performance from the straight line dual cam, it has to be setup correctly. That includes the proper weight distributing, and also the proper position of the cams in the crook of the spring bars.
Also, try to size the spring bars to the predicted trailer tongue weight. Too heavy spring bars will make the ride seem stiff, and too light spring bars may not provide the proper weight distributing.
Another thing to consider is the correct Reese setup for the trailer. IMHO, the round bar setup works best for trailers with the coupler on top of the trailer tongue frame, and the trunnion bars work best when the coupler is on the bottom of the trailer tongue framer. That also goes along with many/most of the lighter/shorter trailers that sit lower to the ground have the coupler on top of the tongue frame, and heavier/longer trailers that sit higher up tend to have the coupler mounted to the bottom of the trailer tongue. Round bar setups go up to 1200 lbs tongue weight , and trunnion bar setups go up to 1700 lbs tongue weight.
I have the trunnion style spring bars on my trailer with the couple mounted on top of the frame, and have had some rub issues. The rub issue occurred when the coupler was mounted on top of the tongue frame, and the tongue frame was 6" or over. My trailer has both of those, plus my trailer tongue frame is not exactly parallel to the trailer frame.....it comes up in front. Going to a 2" raised ball helped with clearance some (per a call to Reese), plus 1 of the newer head assemblies (supplied by Reese after 1 of the trunnion sockets "stretched") with a raised platform helped.
