I did a condensation check on my Tarptent Moment, and good grief it built up moisture in the wet humid night here in Tennessee. In all fairness, I covered all of the vents and had the fly all the way down because I wanted to see how much build up of moisture in this humidity with maximum coverage. When I checked it, the tarp was completely soaked outside and inside, but the bug net remained moisture free and floor wasn't wet on inside. I may have to get used to packing the rainfly separately from the tent body so the rainfly dry out in one of exterior pockets of my packs, or pack a micro fleece towel..
