Handled wind very well, no condensation
Just came back from a spring mountaineering trip up to 10000 ft. with TNF Assault 2 tent. The tent handled sustained 30mph alpine wind very well, only using the 4 corners and 2 tie-downs. The sleeve system distributed the wind pressure well; the side wall did get pushed in but is expected.
No condensation issues even with everything zipped up but an 1-inch hole in the back window. However it is probably due to the windy condition that the air flow is good.
I am 6'2, and I had no issues with the length of the tent. I share the tent with my wife who is 5'6. The space worked, but was not spacious (boots outside, packs inside). If you absolutely don't want to come in contact with the tent wall or want to "stretch out" inside of the tent, then this is not a 2-person tent for you. For light and fast alpinism, it can work well with the exception of rainy conditions.
