It's true, especially if you keep it in a place that gets a lot of heat and sunshine.
Mine went through a severe hail storm here in Austin in 2009, baseball sized hail, resulting in a lot of dents in the roof panel on the streetside. Four years later, and most of them are gone. There will always be a few, and since I keep it stored outside, not under cover, always the possibility of more. I just consider it character.
But, my AC and windows survived. I was definitely fortunate.
Good luck with the insurance company, hope it works out for you.
