as big as we can manage. The other option might be a circus style tent like the 20x20's that can be rented. My thoughts were to use it for a group ice fishing shack, event cook shack, event hangout spot in the rain.
Seems like the largest on that website were 16x24 or so. Almost 400 sq feet. The large ice fishing tents are 6x12 and fit 5 people comfortably. So I'm thinking a 16x24 would hold 16-20 people with the stove set up and going. Could add propane heat as needed too but might not be required once the wood stove is ripping. It would be a substantial invstment of 2k but would be great for some events like fishing and any late fall early spring base camp wheeling. I like that they come with an internal frame. That would make set up much easier.
On the website above they set a tent up in about 5 minutes with 2 guys that know them inside out indoors in ideal conditions. I'm betting in 30 minutes we could set one up with 2 or three people. That might be work it for even smaller overnight trips.
I'm a super impulse kind of guy though so right now I think these are pretty cool. It certainly needs some research and though put into it.
