I bought this tent while hopelessly devoted to SD after years of 5 star experiences with an Omega, including 2 successful Denali trips. But a flat top, really? Woke up with 6" of unexpected snow accumulated and the roof of the tent collapsed in my face. The suspension can't handle it. And plan to sleep head to toe, because the corners opposite the pole attachments sag terribly (even before the snow), & unless you really really like your tentmate, you're going to have the saggy corner in your face all night. The fly iced up overnight & as soon as the sun hit, everything inside the tent was dripping. Pros: 2 doors & ample vestibule space for dogs, packs, cooking, etc. I'm gonna set it up in the yard & turn on the sprinkler for a while to see how it responds, but I'm very skeptical after last weekend. We most definitely exceeded the design limits.
