Allen, I believe Mark summed it up well. As far as protection size, like you said to don't want to underestimate the size of the shelter, so I honestly would conside double your estimate. I think after 5 years with the summer temps and sun you get, an area 4 X 8 would not be an outrageous estimate. That is my opinion, take it for what it is worth. Be sure to let us know how it goes and post lots of pics!!! Great to see you pushing it in Edmonton...
