I haven’t noticed condensation until the very cold nights this year (below zero each night). Even then, it was just a little frost in the corners.
I was able to dry out my boots and gloves by placing them in front of the heater for radiant heat. It works, but not very quickly. A wood stove really drives a lot more heat and does the job better. After an hour or so, all of the snow had melted from the floor. In another hour the floor felt dry.
As
@Newtosavage mentioned, a clothesline would help. These heaters put off a hot stream of air straight up. The difference in heat from bottom to top of the tent is intense.
