I dunno monkey, you might should have put a spine down the middle with pvc too. I think if there is a weak point, it'll be a front to back failure, like dominos. Other than that, it looks strong as heck. It's a very strong shape. We use something similar here at the marina to cover some of our work racks. It was relatively cheap, about 9 grand for ours, but it is huge. We don't really have to worry about the snow and ice, but this thing is rated for up to 115mph winds with the top on! And it only took four of us to put it up!
