The black poly would be on the interior side of the insulation, not on the exterior. I'm currently planning on not having a vapor barrier on the outside of the insulation since I can't take the siding off. If there does happen to be tar paper there, then I'm fine either way.

Great point about the skirting! Critter proofing the floor insulation is also a great idea. I've done that with 1/4" plywood and tight seams and it kept mice out of a cabin very well.
