Thanks. You are so smart. If this plan work for me " I will have to send you some tomatoes next year. I have to make so small adjustments with hurricane brackets because I live next to the water, because of our building code. I when down to Home Depot and they could not believe the green house outer walls will bent in shape to the trusses buy itself. But, I know it will. So I took the design out of sight, because you should sell your design to a companies or builders. .
I will save the adjustment for your note when I complete the JOB. It will take me some time.
