Floor

The floor consists of and 1/4" ACX sheet, a layer of 1 1/2" insulation, and a sheet of 1/2" ACX. The frames where made from 1 1/2" square douglas fir, with half lap joints at the T's and corners. The whole thing was leveled with the laser and shims, although we had to utilize some rocks and welding tanks to keep the ply from springing up on the first round of frames. The frames and plywood, as well as the underside of the floor sheet, were painted with three coats of exterior paint in case of moisture getting in. Insulation was cut from a 4x8 sheet to fit in each rectangular section, then the whole thing was sealed up. It's pretty solid, just a little deformation if you jump on it. I did a few passes with a router to clean up the edges, and it was wrapped up in a couple weekends. I built the tarp shelter around this point to keep out any sporadic snow and rain.
