1. We had 3-4 people for install and we would recommend at least people in final stages.
2. We installed on wood/synthetic decking on a roof top. First night we had 30MPH winds with no trouble (canopy tied back). 
3. Not impressed there were no 1/2 washers for the large screws for tie down plate. We purchased galvanized washers and L brackets (screws) for added strength at base. 
3. The canopy is good quality and looks great. We added tie downs when not in use.
Pleased so far!
