I had to sell my Outhouse because I also found it hard to bowhunt from. I'm 6'2" and when I drew, either the bow would hit the front or my elbow would hit the back making noise. The Doghouse is too short and I was always bent over in that thing. I bought the Roundhouse from Bass Pro. They had it miss-marked and I got it for $100. It is more cumbersome/heavy but once it's setup it's like a hotel room. Best thing I can say is see if they have a couple setup and get inside. Then you can see if they are big enough for you. If they don't have one up, buy it, try it and return it.
Edit: Sorry, got the two models confused.
