A full liner in the Seek Outside tipis eliminates most condensation problems. I leave the liner in all year. My 8 man which is adequate for 2 in my opinion, weighs about 18# with the tipi, liners, xl stove and pipe, aluminum pole and stakes. The 12 man size is only a few pounds more. Drawbacks are high cost and you don't want to let a lot of snow build up on the tent which is true for most any single pole tent. These lightweight stoves heat things up great but don't hold a fire for long.
