I've used a cover on mine for about 5 years. It's NOT a piece of cake to put it on, but it's not that hard either. I lean an extension ladder against the side of the motorhome. I then tie a tow strap around the middle of the rolled up cover and climb the ladder and get on roof with tow strap in hand(cover is still on the ground). I then pull the cover up to the roof(about 35 to 40 lbs), roll it out and let the sides fall down around the sides of the RV. I climb down the ladder and pull the cover over the mirrors, strap it down, and it's done. It takes about 20 minutes to do it. I don't put it on if I am going to use the motorhome in a week or so, but anything over 10 days, I put it on. It's worth it to keep the sun off of it.
