I have the Nallo GT 2, while I cycle the world. It's small, light, and easy to setup with 4 pegs in a matter of 3 minutes if I move fast. I find that if I have my feet towards the sloped end in the morning I have condensation. If I sleep with my head on that end it is fine. I used to think I would touch the inside of the tent will rising but not the case. I've been happy with this tent, and it's certainly got enough storage room for when things get ugly.
You cannot adjust any of the vents from inside the inner tent. You can adjust the front top vent from inside the vestibule. If you have the bottom vent open, it increases the chance for water to seep into the ground sheet for a soggy surprise in the morning.
