We made ours to seat 2 hunters but in a pinch 3 might fit.
Now days they get built 4x6 and they all have a 9x12 pitch roof so even with a hole it has to be a hard driven rain to get in.
They all also have a propane bathroom heater to make those cold days not be so hard to sit all day.
There is enough room to stand up in the center as i am/was 6'2".
