The length of any poles coming up the sides becomes very long. Then the pressure is across the pole, not straight down the pole. So a pole set has to be long and strong... which equals big and heavy.
Best option is to tie to a tree limb or limbs. When I set up an Appy Trails Mk V I sometimes run a line between two trees and just hoist the tent up to it's 6' height, then stake it out.
If I used two poles they would need to be about 96" each, and about 1.5 ", at least at the base.
