I am on my second RV that I have covered and my second cover. It is quite a bit of work to put on and take off but I think it really helps protect the RV from the harsh Iowa winters and also the hot sun in the summer. You need to keep the cover tight to reduce flapping and chaffing in the wind but I think it is worth the effort. I only cover it if I am not going to use it for an extended time. I am hoping to be able to store it inside this coming winter as I am not getting any younger :( BTW, my covers have both lasted several years.
