at 17:00 regarding the Z plastic snap on to prevent leaking, the best way to have them stay on is to tape the back. I'm using Gorilla all weather outdoor waterproof duct tape.

Ok so I'm not the only one questioning what in the world Domi was thinking when they came up with that "Xanny" idea. Those plastic pieces are ridiculous. But, right up there are those darned rubber pieces that you have to fit on AFTER they tell you to put the roof panels on and then somehow get the holes through 4 items to line up to take a bolt. I figured if the plastic pieces are gonna be called Xannies, then we should call the rubber pieces "smackies" because they make you wanna just smack yourself the whole time you're trying to get them into place!

Gutter drain holes at each post?
