Also of note on the Amazon description for the rainfly... It says the rainfly creates a 'spacious vestibule outside' that is 'perfect for stowing shoes and other gear'. Um, how do I put this?... It doesn't. I'm sure that's the description that Coleman provided to Amazon, but even the picture on the storage pouch clearly shows a rainfly that just comes down over the top edges of the windows.

On the subject of that big freaking bag... If you lay it flat on the floor it will measure the full 72"x22" listed in its specs. I had a friend who is 6'2" and approx 230-ish pounds who was able to stand completely inside the bag and zip it closed, much to the amusement of his wife who took pictures before she tried to knock him over...
