Pamela, not at all. You see, I don't want to snug to the ground in all conditions – it's not necessary, and I'd like the ventilation from a slight breeze. However, in windy or very cold conditions, being able to snug to the ground makes the shelter more versatile. In windy conditions, that few inches open at the edge of the fly is going to really catch the wind, increasing tent noise, putting pressure on the fabric and reducing warmth.
Also, you can block condensation from the ground by placing a thin garbage bag cut to shape over the vestibule ground to block moisture – that's what we do with our Hilleberg Allak vestibules in winter – works like a charm.
Chris T emailed in response to the lack of an extended fly: "It's a shame as down to the ground flys would extend the usefulness of the [Tarptent] shelters." I couldn't agree more. That said, Henry pointed out in winter, when there's snow, you could build a snow wall to block the gap between the fly and the ground, or sink the shelter – both good ideas. The problem will be in situations where there's high wind or driving rain without snow to form a block.
I may try to sew a fly extension myself, or find someone to help me with this, as the Scarp 2 is the closest my wife and I have found for a 3 season 2 person shelter that will work well for us in most conditions. I think it's a great tent, and as Henry pointed out, every tent and piece of gear for that matter is a compromise. I just think this one will be near perfect for us with an extended fly.
Time to put on the DIY/tinkerer hat…
