Installed the 2 inch R13 polyisocyanurate insulation in the floor and loft, taped aluminum seams and have 3/4 inch birch plywood over that. This makes for a really firm floor and loft plus the 1/16" aluminum outer skin now thuds when you rap against it...just a more solid feel now.
We are in the process of putting the insulation in the walls, then going to cover with 5mm hardwood underlayment from home depot (nice stuff actually). We need to think about wiring first, and I have done a revamped layout drawing of where things go. The 6000 btu Danby air conditioner is in a shroud on top of the bathroom area (the blue walled thing). Lots of storage around the ceiling since the inside of our camper has 8 feet of headroom.
Amazing how small this camper seems inside when you fill it up with the basics...it was so HUGE when I was welding the frame. My wife calls it the Sidrat (see if any of you can figure that out).
