Hopefully with the double wall, he will make it so that you could also use it as a single wall. I'm sure he has thought of this... Best as I can tell with the Scarp 1, his other DW, the interior "wall" just clips to the shell of the exterior wall. I would expect this one to be the same way.
I wonder if it will have the same shape as a Scarp, or if it will be more of a pyramid style? My guess is that it will be more like the Scarp due to that there are others that already make the pyramid style double wall family tent.
Personally, I'm hoping to see it and assuming I like, have it shipped to me by Memorial Weekend...
