What do you reckon this Cover-It portable garage is worth? 12x30' round house with heavy duty fabric. 12' tall. It belongs to one of my customers and he is moving and doesn't have the means to relocate it. He previously stored a 22' boat in the winter in it. He paid $1800+shipping about 5 years ago for it. I have no immediate use for it right now since I don't want to put it up on my property but I know it would be useful to have for a year or two down the road. Whats it worth??
