Ameristep has a few that are pretty big. I have a hunters view lodge thats 7'X7' but no mesh. Its not really needed with a big blind if you stay back from the window. Its 7' tall too if I remember right. I recently got a Yukon Tracks Commander & like it too. Its a little smaller than the lodge & a person much taller than me (5'8") might have trouble standing to shoot but its real roomy, maybe 6&1/2' square.
The yukon tracks blind you can open the whole top half of a wall covered with mesh. I have a couple dog houses too & like them alot but theyre tight for sure.
