What does the back of the tent look like? Does the fly come to the ground or does it just have a canopy type fly over the back door?
Essentially the rear is virtually the same, but without the door mat. There may be one change however; it has two vents on the rear but only one for ventilation on the other; but that was not the rationale for the question.
Both vestibules are 3'9" deep, along the short side of the tent (one side is 8'4" x the other 10'), or roughly 13 square feet.
