Question about floor

I'm replacing the floor on my '70, 21'. While removing the old floor I discovered a sheet of alum between the plywood and the frame. There was one in the front of the AS between the frame members and the first cross member. There was no insulation under that part of the floor. The other piece was between the plywood and the step mechanism.

The plywood in front was rotten (from leaks) but also from the condensation between the plywood and alum.

Can anyone tell me why these are here and also why there was no insulation under the floor? I'm sure that they were installed at the factory and not from a PO.

The one in front would probably be for if you wanted to mount your spare tire there. The one under the steps is necessary because otherwise the wood would be exposed to the elements, as there is no belly pan there.

Thank you, it makes sense. There is belly pan in the front but a spare was mounted there you would cut the pan out.

Yup that's what I have in my 69 safari that I am doing the front floor in. The front one is covering my spare tire pocket that's directly below it. I did have some thin factory Styrofoam above that panel for insulation, it was about 1/2" thick and the kind of Styrofoam that a big screen TV would have in the box to protect it. I would recommend making sure the aluminum is sealed up if you can access it from the bottom and top. I found a lot of dust in one side of mine therefore that indicates a pretty good air gap. The aluminum above the step is just another protective layer, probably helps keep critters from getting in the the folding step area and chewing through exposed plywood.
