highly recommend the 8 man and sxl or higher stove. 4 dude with gear comfortable with a pile of wood and stove. Condensation isn’t anything that can’t be dealt with as there is ample room to stay away from the tent walls. Pitch location and running the stove helps too.
I highly recommend a seek 8 man and sxl+ stove. Four adults with gear and room to move and stand and stove with a pile of wood no problem. It’s the way to go. Performed well in heavy rain.
I have the same set ups and I spent two nights at 10deg.. not quite as low as you were asking but I thought the tent and stove did well here. I ran the stove all night and would pack it full of wood every hour or so.
