I just spent a week in the woods in my Megatarp. There was a lot of condensation, which I got rid of during the day by opening both ends and allowing the breeze through. I did not have a stove, and the temps were in the upper 20s. A stove would have driven a lot of the condensation off. The ground I was camped on was super saturated. Not tracking in mud was a plus, because it was muddy. One night I got 9 straight hours of sleet, and I whipped out my trowel and dug a cat hole inside my floorless shelter, and was able to not go out in the wind and sleet to relieve myself. I prefer a hammock for most instances, and have used my megatarp over the hammock. Not ideal, but it worked OK, but when I am on the ground I like the megatarp.
