Not to sound like a smart ass, but can you take it back and get a bigger one?
I've got the Cabella's Lightning Set pop up and it is 84" X 98", room for two, if one of them is not me! (lol) Plenty of room, excellent features, and comparitvely affordable.

If none of that is doable, maybe keep the door area to your back and up against a tree or bush or some fresh cuts to hide your back side. At least that way, you are still covered in the front in the area you hope the critters come from.
