one fortress do sell a number of mesh inner tents that will fit inside a number of tents. I dont know if this would help with condensation. although unlike the tipi style tents if you put an inner in the homestead I dont think you have room for a stove,
My previous tent was a Oztent RV1 and that being a single skin tent also suffered some condensation issues. It is not a big problem if you have room to keep away from the walls when sleeping but you dont always have that luxury
