Lived in winter snow and in summer with the Ventana. Best tent I have ever had. Cannot hold a snow load at all, so must be tarped, but it is a real house because: 1)the ventana never ever gets wet from humidity. It is all screen and stuff dries in it even in the rain. 2)It is incredibly spacious because the roof arches up a away from the center. Two people can move around and the walls are always dry. 3) The fly can remain open to look out like a window during rain storms 4) Then entire rain fly sits tied on the roof of the tent for shade and then clips back down in a jiffy on any side you want.
Drawback: my tent completey got flattened in a sever thunderstorm yesterday and the lead poles bent. Guess that's why they are guaranteed! Nb. My stuff still stayed dry though.
