I use the Adco cover, too. No problems other than the inconvenience of having a cover and not a full-sized garage. Easy to put on and take off. I roll mine out on the roof and just throw the sides down one-by-one (I think the instructions tell you to use a ladder and move it around the coach); my way is faster. I leave a couple windows cracked in the coach to avoid the moisture problem. \ken
