Adding the Insulation and Installing The Floor
These pictures are part of that mysterious "missing roll". I know they're somewhere, maybe still at Costco. Anyway, I bought about 1 ton of insulation, Level 2. According to the diagram, Level 1 is good for really hot, humid weather, like Florida. Of course, Home Depot doesn't sell Level 1, so I had to get level 2, the next hottest-weather stuff. Fortunately for me, Level 2 is adequate for Tampa and Northern Florida, as well as most of the states I'll be traveling through, so I could make do.
This was probably the easiest part of the conversion. We simply cut the stips of fiberglass insulation to fit between the ribs of the floor skeleton and screwed the floor boards on top. The fiberglass was probably about 3-5 inches thick and the ribs were only 2 inches high (factory cut 2x4, so it was actually less than 2"), so when we put the floor boards on top, it compressed the fiberglass supporting the floorboards fairly well. Just in case, we also screwed down a block in the center of each rectangle underneath to add support to the floor panels. Then the plywood was cut. We used 4'x 8' plywood sheets of 5/8" thick. These were screwed to the ribs using 1 1/2" machine screws. The reason for using machine screws is because they were the only screws I could find in Home Depot that day that were both 1 1/2" long and had a flat head.
Below is a diagram (not drawn to scale) showing the layout of the frame and insulation. The brown markings are the wooden ribs and support blocks. The pink is the insulation (duh), and the yellow is the "cab" section of the bus, which I haven't started working on yet. All work so far has been done from the beginning of the "passenger" area to the back.
