6 pounds for a two person tent seems heavy. Maybe you have a 3-person tent for the two of you, but this certainly seems like one place you could cut some weight. A pound of toilet paper seems a bit excessive, but maybe that is just an estimate. Do you usually bring back a half roll or more? 2.5 lbs for stove, pot, and gas seems a little high. There are lighter options than white gas.

Those are just my thoughts... but in full disclosure, I am a failure at ultralight too
