I ended up using tarp clamps made for trucks. I think I spent too much money on them @$1.30 ea. Oh well. Those are the things that will last and take up little space in storage. They went on like clothes pins. Plus, there is a loop on each of them. If I want to I can string a cord through it holding the tarp down even further. I am contemplating using clear vinyl for the door openings. You can get it at fabric places like Joanne's etc. But I think it is sold by the foot so it can get expensive. Comes in 8 foot widths. I am still trying to keep somewhat incognito from the HOA.
