Well, I hiked the CDT and the AZT with one silnylon Tarptent without a ground cloth. I didn't have lava, goatheads, cactus and rain at the same time, but often two at a time. The floor was flawless when I retired it, after a zipper failure and a tie down point on the canopy started pulling apart. I found a way to travel without that vital piece of equipment, as well as a few others.
