Step 4: Build awing
Finally I built a collapsible awing out of square tubing and corrugated metal roofing. I next installed thermometers
I built the horizontal racks from expanded metal and angle iron. For the vertical tank I purchased 4 22.5" round grates similar to the ones you can find for a weber grill. To mount those I simple welded pegs inside the tank and the racks just rest on them.
