One important thing I forgot to mention...
It is really more of a tent review, but it is a contrast to the original tent so worth mentioning. As you know the original tent is very heavy military canvas and pretty much bullet-proof. The downside is that it is very dark inside day and night and *hot* on sunny days. The Tepui tent is lighter cotton-poly, has better ventilation, and the silver/grey rain fly and annex make the tent MUCH cooler during the day (I took a nap every day in complete comfort) The material also lets in much more light. IMNSHO, both "features" make the tent more livable, especially in sunny climates.
