OK.....a minor change 5'x5'x6.5' is the cab size now. No more changing cause I bought the wood and shit now. I will start tonight and take pictures. Might not post them tonight because I will be to dog ass tired, or shmashed, which ever comes first. Ya, FF I don't think I will have any bugs or mold (I hope). But my venting from each room will go directly outside, and I guess if the fans stay on 24/7 no cold air, bugs or any type of mold problems should come up. I stayed with 6" through the outside wall with 2 fans "Ted" off. If it becomes a problem than I will step it up to an 8 reducer and make my outside hole larger. I just can't make the hole smaller no matter how much I cut it. :mashed:
