Big tents are also good for other things. Like camping at 800 feet on the Kaibab plateu to hunt muler deer for a week. You need something big enough for hunters, gear, clothes & such. Might as well be comfy.
I have 2 tents now. My 8 man Cabela's Alskan Guide tent, served us excellently in the Arizona high country for hunting, and a 2 man backpacking tent that weighs less than 5 lbs & rolls up to an 18x5 inch bundle. That one made a Grand Canyon rim to river hike.
I had another large tent that i bought cheap. It's purpose was to be the cook tent in the mountains, as it's not a good idea to keep food in your sleeping tent, or cook in it, in bear country. So we'd set up an extra tent & put the coolers, stoves & grub boxes in it. Not much need for that around here, so I sold it to a friend to use for family camping.
