Condensation - it does really well with condensation if pitched tall with 130-140 mm poles to get the entire skirt up. If pitched down, you can easily vent by lifting the doors a bit. They will get flappy in wind, but rain still funnels down so the door venting is a tradeoff that works great most of the time.
48" between the poles. The geometry is tricky but works great. The tent is small at head and foot and big at your sides, so most of the space is reachable.
Even though it's fairly small, sleeping on the diagonal I squeezed in a 7' long X 8" tall cot (go-cot) with a 3" thick X 30" wide sleeping pad on top and could still get the doors closed fine. I was really surprised it fit.
The geometry really maximizes comfortable, usable space and minimizes space you don't need or use. So max usable at minimum weight. The sitting headroom feels huge for the size.
You can sleep two opening to opening more like a two pole a frame style tarp. It's a little tight for people over 6ft tall , but for a bivy, spike or UL setup certainly do able.
