Did a test fit of the floor before painting the frame.
The frame is stripped down and painted.
Installing the floor, the bottom layer was painted on both sides with herculiner (weather resistant paint).
Then a layer of insulation.
The insulation is sandwiched between plywood. Both layers of the plywood are 1/2 inch and the insulation is 3/4 inch.
You can also see in the pictures above that the frame is wired for the lights, solar panels and the fan.
The next step is to put down the flooring. We were going to go with a bamboo flooring but with the temperature changes while camping in the cold and heat, the flooring would expand and contract and cause it to split. So we are going with a laminate flooring. After the flooring the inside walls are going to be installed.
