I'd want multiple tents for 8 guys. One good sized wall tent with a wood stove for eating and hanging out. 2 or 3 smaller sleeping tents which may just have Buddy heaters for dressing. Just turn off the heaters once everyone is in their sleeping bag. Much easier that way to keep a fairly neat camp. Also less likely that the camp slob will annoy the others by leaving his stuff all around. Not to mention the guys who snore loudly. Put them in one tent.
