Seen em all fail at one time or another. Deans, Pats Aurora ect ect. They've come a long way over the years but will still fail. A pocket full of quarters and 10 minutes at the car wash will cure travel grime and a hell of a lot cheaper than a glass repair. Maybe I'm old and set in my ways but I was taught by the best and oldest in the Champion biz. For the record I have a custom made Pats cover that came with my rig that is very nice and well made. I've towed with it once from the former owner home to mine and rarely use it unless stored outside, which is once in a blue moon. Your rigs, do what ya like, this is "Merica" after all.
