http://wheelskins.com/ Don't know about your size, my computer is working slow today, but check them out. A good cover is like a good fitting glove or favorite tool, after you use it, just feels so good.
The adage of "you get what you pay" for is true here. You can see they are not cheap but they sure are nice. I haven't tried all that available but these are sure nice. One in my pick up is over 10 years old. One in Class C is about 5 years old. Both of them as good as when they were put on. Which took me about 3/4 hour.
