I used my Fitzroy for the first time this past weekend. I had the vestibule attached with the zipper unzipped at the peak near the vent. I then had the larger tent door (the one in the vestibule) vented the same way, with the door unzipped at its peak near the awning. Finally I had the small door vented not at the top near the awning but at the bottom, I had the whole bottom unzipped.
It was a very still and clear night, the temp dropped down to 12* F. We woke up that morning to the whole inside of the tent and the tops of our sleeping bags full of frost. Now I did not fully expect the inside of the tent to be frost free, but I didn't think it would look like a freezer inside!
Am I venting the tent properly? What ways do those of you that have this exact tent vent yours? Should I come to expect this on nights like these? or every cold night? What about semi-cold(>30*), damp nights?
Any info would be appreciated.
Thanks,
