I have seen this with a number of motor homes. I have a set of seat covers that help and I always place those cheep silver sunshades in all my windows between the glass and the shade and windshield. They protects the pull-down shades and the seats. I updated my seats this year it wasn't that expensive. I even added the swivel. Shop4seats.com but there are other places.
New to site ~ we have a 2010 supernova 34' that I love. I pull a 3 horse trailer and all the gear for our horses. 15,000 lb towing package I believe. My daughters and I go on our own a lot as hubby has to fund our trips 😉. I love ease of use but what I don't love is that the "leather" furniture (couch and driver/passenger seats) are sheddubg like snake skin. I am very disappointed in the poor quality. Has anyone figured out a way to make cab noise less? I can literally see daylight at times. I have tried over the counter weather stripping of sorts and it is better but not the best yet. I get lots of compliments on her and am pleased with her towing abilities so far. Any suggestions, resources for furniture etc. are appreciated. We are in Texas and have found very little info.
