NOVEMBER 1 UPDATE:
The floor is finished! (well, 99.5% finished, as I still have to put in trim pieces at the side and rear doors.)
Starting with an empty van:
the next step was to add fiber insulation -- just the fiber matting used under carpets -- to the troughs in the floor. The purpose wasn't for thermal insulation, but rather to fill the empty space that would become lots of little metal echo chambers:
With that done, it was time to make a pattern for the subfloor. The cardboard pieces were 4' wide so that they would match the sheets of plywood. The filthy carpet made a good pattern:
and with a little trimming, the cardboard pieces fit correctly. The bolts (12mm x 1.75 60mm) pass to threaded holes in the van floor (seat bracket holes) and will be used to bolt furniture:
It was time for plywood. I used two sheets of 11/32" (nominal 3/8") BC plywood each cut to 4x6'. There are two solid sheets toward the front of the van, and the aft-most row is made up of the two "leftover" 2x4' pieces:
Per
WVvan's question, I decided to run the flooring up to the Ford door threshholds, and not cover them; in this photo, you can see that the tin box covering the AGM in the stepwell has been covered with a plywood box (painted with plasticized paint, which was a mistake; it will get a new paintjob at some point).
Because the plywood fits well, and there are floorbolts in each section, I used very few 6x1" sheet metal screws (they were not easy to install!): screws were used sparringly along the seam lines to ensure smooth, level seams. The finished plywood subfloor:
For the final layer, I decided to use Allure vinyl plank flooring. This is a floating vinyl floor: the planks glue to each other, not to the subfloor. This is supposed to help with expansion due to temperature variations, but the instructions say not to expose Allure to temperatures > 95 degrees for extended periods or the glue may fail. Hmm. Texas summers? Nonetheless I decided to use it as it is recommended for vintage airstream remodels, and
NRL on this list has had good experiences. It comes in 4" x 36" planks, which are much stiffer than regular vinyl, so I have high hopes for its durability. It is waterproof, and if necessary individual planks can be cut out and replaced.
The blue tape marks the locations of the eight bolt holes; I have yet to drill them out <gulp!> The trim pieces still need to be installed, but here's how the side-door threshold looks.
So, other than drilling the bolt holes, adding the threshhold trim and putting a few more tacks in the carpet/floor seam at the cab, the faux teak floor is done!
Onward to building the interior.
) to do that! I will do all design, woodwork and fabric work.
Oh, please don't apologize! 
) yet, which I thought would be dull to other forum members, and I didn't want to monopolize the forum. I have learned a tremendous amount looking at all the other galleries and asking questions which you have kindly answered -- curiosity is good! Please keep asking so that I have an excuse to talk about my van project!
