Is the MARK2 the only Clark Hammock model designed for go-to-ground?

Some of the other models looks pretty tough, so I'm wondering if they are suitable or not?

I'm in Australia and plan to do most of my camping around Australia, but I'd also like to take it overseas occasionally. In Australia the summer is mid 40s 'C (104-123'F) and in the winter snow the extreme is -23'C (-9.4'F).
