My biggest gripe with this product is they should include an extra B & A connector. As you are pulling the tarp over this will put a lot of strain on either an A or B connector and in my case the B connector split where #6 joins A. It cracked probably because the connectors are not the greatest quality ABS or are not pure ABS and use other cheap plastic. Rubber connectors would be better and add weight, but also more expensive. Metal supports are a tad too thin for my liking. I have my doubts that the metal is galvanized; rather it is probably just painted. The Tarp is a tad too tight for easy install. Really it's a particular pain to try to get the cover fully over. Grommets and hooks would be better than velcro especially for the cover. In fact, if you just increased metal thickness by 0.15\", used rubber connectors and a cover with grommets and hooks, it would be a vastly superior product and much easier to assemble; Amazon could charge 150-160$ and that would be fine.
