Thanks for posting. This same repair would apply to more units than what they listed. Clearly, Keystone should hire someone with engineering experience to prevent sort of thing from happening in the first place. And then they continued this design for years.

Yup the problem has been going on for over two decades across many different brands.. I made a quick check of my unit and have barely 1/8 inch of difference with weight on the LG and then weight on the truck with LG up..
