@RobinH - we managed to get the cover on our coach, but because the “front” tag wasn’t easy to find (it should be sticking out like a sore thumb at the top of the storage bag). we got it on backwards. There really should be installation instructions included with each cover, including how to tie it down with the long length of cord sent. To be honest, I was very disappointed. I couldn’t recommend this cover with these issues.
