Back to tents, do you really need an 8-man tent? Is that because you love snoring and stink?
5/6 would be the absolute biggest I would go.
i would be camping w/ three other humans most of the time so four total. i don't know that i need an 8 person one but i mean if i'm going 6 then why not just go 8 kind of thing. are there drawbacks to biggers ones. i mean idk, but more room sounds nice.
I get it. But it seems like 8-person is kind of a tipping point. It's either crap quality or a $1,000 Everest Base Camp job. So, you can get a 6-man tent from a reputable manufacturer at a reasonable price that will last a decade, or a slightly-bigger, way-heavier Coleman (sorry, Wichita) that you'll most likely have to replace in six to 24 months.
Tell the kids to keep their stuff put up and you'll have plenty of room in a 6-man tent to play cards while it's raining.
Two four-man tents would be a great option for space/solitude.
