In reply to Keen2go:
I have used a similar tent for the camps for Pisco and Tocllaraju with no problem. Adequate shelter is available at both sites. I have also used it for various base camps at c5000m in Nepal and India and in the winter in SW Tasmania.
For the second camp on the SW ridge of Chopicalqui at 5600m and the second and third camps at 5400m and 6000m on Huascaran, it would, IMO, be rather marginal. I suggest that you only use it if the weather is forecast to be stable for your climb.
