I'm probably going to be redoing the floors in both my boats this year, and I have no indoor space available to me. I'm considering buying one of those "Garage in a Box" shelters, but I hear a lot of them that are junk in a year- or even sooner. I assume some of it is a get what you pay for deal, but I'm wondering how cheap I can go and still have it be worth something next year? A 12'x24' or something can range from a few hundred to a few thousand. Any suggestions?
