So, took the 3-man £30 jobbie to the middle of the Nevada desert, staked
it out & kept it there for about a week through an 80mph wind storm and
105degF days.
Result: after two days of winds, started seeing light through some of
the seams of the base, luckily no rain, but wouldn't figure it standing
up to too much. The tent stayed up throughout, using just the normal
pegs (I was certain the poles would snap at one point). Ventilation -
quite good, with the porch open.
Tent considered sacrificial at the end of journey (more room for other
things), but would buy one again for the same (dry) purpose.
