Important piece of advice. The instructions tell you how to put together the roof framing. The don’t tell you not to do it on the ground. I started out that way  with zero success and then constructed it at roof level by using an extension ladder as a scaffold to support the center structure and tied all the roof trusses to it. Made all the difference in the world!  Plan on a day to day 12 to put together even if you’re handy. Lots of pieces. Instructions are pretty good. Do yourself a favor and follow them closely (notwithstanding what I just said about the roof framing). Don’t try to cut corners. It’ll probably end up costing you extra time because you’ll have to go back, take something apart and follow the directions verbatim anyway. Have fun and enjoy this monster
