I have an older model of this tent -- has sleeves instead of clips and the doors aren't mesh. It's done fine in sub-freezing temps -- Minnesota/North Dakota. Condensation will collect if you have the fly closed up for the night but it hasn't ever been enough to drip through the mesh. It saved me one time when a microburst came through early in the morning and tore a huge branch off of a tree overhead. It bent up the poles and tore some holes in the fly. It would have kept me dry except that the walls were collapsed because of the weight. I patched it up and re-shaped the poles and still use it. A normal 5x8 ft. tarp/ground cloth fits it fine (excluding the area under the vestibules). Just keep the edges of the tarp under the tent or rain will drain off and pool in between the tarp and tent floor. You'll still be dry, but you'll be laying on puddles of water.

The temperature ratings were accurate and it was comfortable. Used the liner with an old Kelty mummy bag in Voyageurs National Park (Canada/Minnesota boundary waters country) back in September. Low temps at night were in the low 40s. Didn't have to deal with any extreme weather, just a little rain a couple days in. I enjoy the flexibility of the liner and I saw it as an easy way to keep my sleeping bag clean.
