Does anyone have experience with the harbor freight or shelter logic portable garage products?? My sister has allowed me the use of a single car concrete slab next to her garage to store my new PUP and I'd love to have a way to keep UV off of it. The above products in the $200-350 neighborhood are very attractive. If they only last 3-4 years I feel the cost would be worth it. Still much cheaper than indoor storage by a great deal. If anyone has some experience with these products I'd be delighted to hear about your experience. I'd call the budget $500 for something that would last a good number of years, less for something good to last 2-4 years.
