Search for J skirt for the metal & Icon Technologies for the fenders. I did one on my last 5W took a couple hours. I pounded the damaged fender flat for a template. On mine there were some hidden screws under the trim strip. I was able to carefully open it to get to the screws and bent it back when done. That was a Jayco but they are all similar. CW wanted $1300 and a day. Long story short that went down hill and I ordered all the parts needed for $250 + $250 shipping. The J panel was 10 or 12ft and I had them cut and ship to save over size shipping. I think I could do it in an hour now. Good luck.
