Hello from a newbie (and a Keystone question)

I have a Husky WD. It has round bars with chains and friction sway control on one side. There was no manual with the unit and I went to Husky site and it asked for a model number which I don't have. BUT looking at internet for others they all seemed to give basically the same instructions. I followed them and discovered that when the previous owner installed the hitch on my truck, as part of our taking the TT, it seems he set in close to what he had. He had a F150 as TT and I have a Chevy 2500HD. I had some bouncing on the way home. Taking it apart, I saw the trailer level at about 22" and the inside of the coupler was at about 23". The ball height on the unloaded truck was about 18 1/2". So I raised the ball and reattached.

Thanks for all the comments!
