Because my buddy wanted the big overhang for the snow, the weight made it a bit tippy so I had to secure the back with a couple of steel poles into the ground.
The other mistake was he insisted on a big shooting window, but to me it was to big, so we enclosed it in a bit with burlap covering.
The inside is blacked out with a few cans of black spray paint.
This thing is like a bunker, 2x4 spaced 16inches, be there long after I am gone.
Because we used the floats you have a full foot snow clearance to step up and into and I suspect the insulated foam filled floats and plywood 1/2 inch floor will keep the rising damp out.
