another description of the steps from a different source.
"The layers will go something like this. Trailer deck, metal flashing, 6 mil vapor barrier, treated wood framing filled with foam, then plywood subfloor."
The 2 biggest differences between this and the tiny house on the prairies folks seem to be this guy is using a vapor barrier (like Tyvek I believe) and he used foam insulation instead of wool.
