Chaz it been a while since ive been on but read the last couple pages , Use One Fan, Yes One Fan for the Whole Thing. I have Already Told You about it before Can Fan , MAX FAN 8" HO the thing will pull 950 CFM's, more than enough to cool your 2 tents. Connect the tents in line and call it a day!!!!!!
