I only want one tent, for winter an summer...
I only want one tent, for winter an summer use, is this tent a too hot for summer? about 86 F. excess condensation?
You'd probably be pretty miserable in 86 F inside this tent. Depending on what kind of winter use you have in mind, you might not really find an option that does both. If your winter use is just on the snow/cold/rain...and not mountaineering, then I'd check out the Bibler Ahwahnee or something from Hilleberg (not sold here currently). Of course the Ahwahnee is a two person tent, so it might not work for you, but Hilleberg has several options that would be decent.
