We had the "Conqueror" with a dome tent up top and a stiff...read that STIFF wind in Death Valley was never felt.
We await the arrival of our new Horizon and will have it with us later this summer. I'm sure that we'll be exsposed to winds here in the NW and later when we take it to Baja, so will have to postpone any empirical data for a bit.
I will say that last January we were in a horrific wind in Namibia and a couple of girls were camped near us (Sossuvlei Dunes). The next a.m. I asked if they were blown about and they responded that they felt only slight movement. At least, that's what I think they said. Mein Deutsch is nicht gut.
