What I did was support the sagging material the screws and screw caps. I gave it a quilted appearance with the help of my mother in laws quilting experience. Some people may like this, some may not. DW is happy so I'm happy!!
Here are some pics before and after. I would have loved to have the panels replaced. But then this could happen again possibly. Forest River was going to supply the panels and some labor. But the labor I would have to pay for was still going to be expensive. I was able to do this for $130.
