Maybe so, but it looks like there's enough space in that room that just by opening the window some you could mitigate that. That's where I was going. Don't get me wrong, there's not a thing wrong with what he has going on, I was just suggesting a more streamlined approach.But he'd still be venting into the room, keeping the warm moist air recirculating back into the tent.
By shoving it out the window he gets rids of some of that.
