Duece, when I had the ameristep regular doghouse, it was tight 5'x5'x5'8".
I had to position my chair in one of the back corners. set your chair where you can draw your bow and not hit the blind with your elbow. anothers words when drawin your bow, it should be facin towards the front corner, that will give you room. you won't be able to shoot out of but two windows, so you'll have to place your blind to where the deer , turkey, whatever will pass by those two windows. or you can get a bigger blind, like the doghouse TSC which is 68"x68"x64" tall and set you a swivel chair in the center of the blind, and you can shoot out of all the windows.
