I have a friend coming down in two weeks who can bring the tent if I can find the right buy. I am humbly awaiting your words of wisdom that will set the world right again. Ron Cunningham, Peru, A difficult challenge. That's technically a two-person tent, but all that means is more room for you. Very sturdy, and at three pounds 12 ounces plenty packable when the donkey is on strike.
Alternatives are few.
Virtually all tents that I'm aware of and that are made for one person are designed as light backpacking or bicycling tents. In other words, not very rugged. Well, not completely stuck. So it would fare well in all but the harshest winter weather. As a bonus, you'd have plenty of room inside.
