I think that can happen in any shack , depending on the temp inside/ outside and the humidity . Sometimes i boil a few hot dogs on my 1 burner port. stove which creates a lot of humidity , causing the condensation to rise to the top. After shutting down the stove the canvas cools way down creating frost on the top. Waiting a while to fire up the heater in the shanty. When it gets toasty in there , it melts the frost and drips down on me .
