If this is the awning that came with the MH, I would be more inclined to replace it. They are not that expensive and since you are going through the trouble of removing it, just do it once. There are newer/better fabrics out there that will stand up to the elements a lot better. We recently replaced all of the covers for our slides outs and WOW, what a difference in material.
