I've had an experience were with an empy trailer and the bars set with to much tension, the back of the truck was too light and was a handful to drive. I bought a 24" enclosed from a guy who used a motor home to tow, he showed me how to set up the weight distrubution hitch and he set the tension to what he used on his motor home. I had a 2500. I wanted to sell tha trailer as soon as i got home if that was the way it was going to pull! After a little research, I tryed without the bars and it was much better. Loaded i would use the bars, empty, no bars. Note: The weight diastrubution hitch I was using did not have sway control.
