Yeah, the materials do keep getting lighter Richard. But we are the ones driving that, right? I do most of my hiking in California which normally sees little rain at night when the tents are up. That is why I try to get them used in Minnesota. The storm that it was in had water running under half the tent for about 20 hours. In the picture with the wind shoving the pole over the tents set up on the property line with the place next to me so the kids can see the tent outside their windows. There is a dip right at that line which is between the right side and the center stake. That became a creek. Not a bit of water came through. My Tarptents have seen some wild weather too with never a leak.
Thanks David. As far as the MSRP we go with what they say, not what retailers sell it for.
Marc, it can set up on rock the same as a Hubba. You would need to wrap line around rocks through the stake loops to pull the vestibule out the same as you would the MSR. My four stake comment is to use the vestibule normally. Something needs to hold one end to pull from the other.
My feeling is that a tent should be able to use all its features. A vestibule is pretty important to me, especially when sharing a tent. That is why I include the weight of as many stakes as it needs to do so. (I will make sure to clarify that.)
