Sorry I can't answer your question either but I can welcome you to iRV2. We have a wealth of info here so don't be afraid to ask questions. I would suggest you repost your suggestion on the Winnebago Industries Owners Forum. I believe you will receive more replies there. Post often and share your RV adventures with us. I am interested in hearing about the solution to your sagging problem.
