I have the fan outside the tent... saves space.... as you can see from my pic... im using an oversized filter for the space just so it actually works. It also allows for the insulated ducting on each end of the fan.... paranoid about possible g the neighboursI use the straps that come with the tent, and I let it dangle. I think those were for strapping up the carbon filter... Which I have hanging with a rope ratchet. Keeping off those poles is a big help. Never tried bungees. I do however use Bungees to help hold up a little with my air circulating fans.
