Love the carport. It is definitely much easier to build with three people instead of two, and I would plan on it taking a full weekend.
I highly recommend using an automatic socket wrench with a 10 mm socket, along with the matching Allen key for each side. If everyone helping has their own wrench and Allen key, the build goes much faster.
The directions are not amazing, but they are not terrible either. Just pay close attention to the screw holes for the roof on each piece of the frame.
Overall, this is an awesome carport and I am really happy with it.
