I agree about the liner, totally unneeded. I never had enough condensation on the inside for it to form droplets big enough to fall onto me. Cracking little tent I love it, I just dont see myself being able to camp again for a long time
bungy jumper: research the tent a bit more and you will see the 'inner' is sown into the tent, its a single skinned tent with bug netting and bathtub floor sown in. If by ridge pole you mean the crossing pole, yes they are both included in the sale, I just never used the crossing pole personally.
