Tom, I have the Carefree of Colorado slide out covers on my MS. I had the dealer install them and as I remember it took them about 2 hours per slide. They have a nice sturdy plastic cover to protect the awning material. I have had the Dometic covers before and I like theas better. They cost more but I believe there is more quality to them and should last longer. Take a look at this site, they are the ones that I have.
