As most portables, easy to set up unless windy as hell. Can set mine up in about 30 seconds or so, that is when I'm not sipping a cold Busch light at the same time. The 6120 is real roomy also. I had 8 holes in it last year with a buddy of mine and could have probably put at least 2 more in it. Not sure how tall you are, but I think it has a 6 1/2 foot clearance in the center. I'm about 5' 10" and I don't hit my head anywhere except maybe getting in the door.

I also run a sunflower heater in mine but wasn't out when it was real cold.
