Hi Alan
I have the Outdoor revolution Spacelite, which is similar in concept but quite a bit larger. Yes, it is still a bit flimsy compared to a full awning, but it does work well. I do not leave it on the side of the van though, as it only takes a few seconds to slide in and out. Only the roof fabric folds into the awning rail bag, the front panel zips out and packs away in a seperate bag with the pole. The rail bag does appear to be waterproof though. It takes me about 15 minutes to erect by myself, whilst kids watch and "help" by running off with the pegs.
It came with everything required, including storm straps, although I am not sure I would leave it up if the wind starts blowing hard though.
I am pleased with it, and would certainly buy another one.
Cheers
David
