I've used a Hilliberg Nallo on quite a few Alaska sheep and goat hunts with few to 0 problems. I would agree that it's well worth having a 4 season tent to deal with super high winds and possibly deep snow? I'd bring along a bath tube footprint if on the tundra. The Nallo and a couple other Hillebergs have almost verticle walls with a super large vestibule area. It's always good having a vestibule for gear and cooking. You may also want a tarp for extra gear and possibly setting up a lean-2? You may want to consider an electric fence to bear-proof your camp when you are gone?
