I don't think anyone answered your question re the large footprint and staking the vestibule doors straight down to minimize the size of the overall footprint. Despite Mr. Shires insistence that "it just isn't that big", I can assure you that it is a large footprint indeed. Plan on needing a space approx. 8'x8' for pitching this palace. It's huge if you're a solo hiker like me that is accustomed to smaller accommodations. All the space is awesome, just be prepared to find the space to pitch it.
The short answer to your question is no- not without a whole lot of extra material flapping in the wind anyway. But, as coincidence would have it, I had the exact same concerns and emailed Henry Shires about making some modifications on the vestibule doors on both sides of the tent, so that I could stake one vestibule or the other straight down. He ended up adding an extra tie down on each door to stake to the ground as well as a hook and a loop to one of the doors in order to gather the extra material that you wind up with when the material goes straight down instead of being extended out. Thanks again to Henry for that solution by the way.
I literally just got my SS1 yesterday so I have not field tested the mods yet, but they look very promising experimenting with it set up at home at least.
With the vestibules being about 3' wide on each side, this mod effectively makes the overall footprint more like 5' by 8'. In some of the terrain I camp in (desert sage and canyons), this can make the difference between more readily finding a spot to pitch the tent or slogging on in hopes of finding a larger site.
Hope that helps you- and anyone else wondering the same thing. I was wondering if I was the only person that thought of this!
