My A & E Slide Topper's are approximately three and one half years old. The fabric needs to be replaced. I have been told that replacing the roller tube assembly with a new one is about as cheap as replacing just the fabric. I would prefer to replace the fabric myself and save a few dollars. If anyone has accomplished this task and would like to share their experience via step by step instructions, I would appreciate hearing from them. Thanks Will Albuquerque, N.M.
