Impossibly luxurious! Two tents? I guess you need that to deal with North Country downpours.

In the arid southwest when backpacking on the Colorado Plateau in particular, one can't easily carry two tents, but one can take advantage of rock shelters which will keep you bone dry in the heaviest storms.

We know this because people long ago figured out the advantages of living in these rock shelters and have left fascinating perishable remains to fascinate archaeologists (Mesa Verde National Park is the most well known example). Fortunately I have been able to excavate in some of these locations and I have personally experienced their advantages during heavy rains.
