Pitching a tunnel tent in the wind is pretty important, I've had my Shires Cloudburst tarptent in some pretty high winds , it held up but I think pulled some of the stitching out of the guyline anchors.. However, if not properly guyed down and tight, a crosswind on a long tunnel tent like the Cloudburst turns the thing into a huge sail and can flatten it enough to be scary... Camped at 6000' in Wrangell St Elias with the tarptent, with huge winds and my friend and I decided to repitch the tent for fear of breaking a pole. Of course the Shires isn't a 4-season tent (nor were we really in winter, just high up (relatively) and exposed to winds rolling down the glacial morraine.
