I would have chimed in earlier, but I was thinking changing bag sort of tents. This is what we got for car-camping with our triplets. Well made, very roomy. We bought ours about 15 years ago, so the tent names have changed, more sizes, but looks about the same. My ex has it now. We did break a pole when we set it up at Zion without guide ropes. I left for the day to photograph and a thunderstorm came through with high winds. Tent came with a repair kit, so it was fine for the rest of the trip.

An old packer I met just used canvas -- he'd re-coat every once in a while with Thompson Water Seal.
