Awesome work as always. I remember that truck, the scenic route truck. You did score on a lot of good parts.
Now, if I may add. I would add a layer of foil backed jute on top of what you have put down already. And again, use your foil tape to finish it off. Maybe your already planning on putting it down. But if not, I would highly suggest it. You can order it by the roll from Home Depot online. It's a lot cheaper than the truck places. Then your carpet can go right over all of it.
Here's a pic of mine, you can barely see the FatMat under the foiled jute. There on the edge where your side sills go, I would not put any jute. It will make it harder to get the side sills on.
