We have a 2018 Miramar 35.2 and I wanted to replace the shades also. We have not had any damage but listening to them rattle against the walls while we drive makes me crazy. I looked everywhere and had no luck. Then one day in Costco they had a display for home window shades and the company (through Costco) said they could install them in the RV. They came out and measured and I picked out some shades. However it was going to cost too much, I have to wait. But long story short, I think the only way is through Thor or have them custom made. Good luck!
