I have posted another picture at PBF however this may illustrate the point a bit better.
The Scarp is provably one of the most suited solo tents to have a hanging clothes line under it..
Just install a line starting from the top of the inverted V strut , going up to the outermost clip that holds the inner up and down again to the other V strut.
This still allows to attach the inner up losing about six inches of floor width, but that still gives you about 26" of usable width.
That blue mat is 20" wide
