It's amazing how much noise comes through a hole in the floor.

Had a true POS company van like that. I took packing blankets and spring clipped them to the roof cross member behind the seats. Got it down to a dull roar. While it's all stripped out consider routing some ENT(Smurf tube)
that the communication techs use to run wire through. Run pull string through it. You never know when you will want an extra wire.
Good luck with the project.

Update, with progress and pictures!

Sprayed Bully Liner on the floor, full coverage with Kilmat plus a layer of 1/4" closed cell foam. 5/8 plywood over that, with 3/8 plywood fender boxes.

Pop out windows in the back and side doors.

Cured the rusty old bumpers, KC lights, and a Redarc brake box.

Passenger side swivel seat base.

Lots of general maintenance, new tires and shocks, and recovered the headliner, changed to a late model console, and put in a shelf-it over the windshield.

Then the big one, the trip to Fiberine for the 20" aero top. Went great, the folks at Fiberine are a class act.

Now I'm working on insulation, overhead cabinets...

Looking Good...

What did you use to fill the holes in the floor with?

I used some Dorman plugs. I mixed up some epoxy, dabbed it around the hole, on the bottom/stem of the plug, and covered the plug after I put the plug in.

I'm thinking that sealed the hole, adhered the plug into the hole, and the top coat will protect the top of the plug.

More details on the Shelf-It, please! First I’ve heard of it. My old SMB had the SMB-installed shelf but my new one doesn’t. How well does it fit, quality, etc.

I'm pretty happy with it, but they have changed the design a bit from the last one I had.

The shelf has brackets that screw in where your sun visors screw in. The visors go back onto the bottom of the shelf, but reversed (they flip back towards you to go down).

You have to do a bit of work to move the center supports for the visors down to the shelf (drill a couple holes and trim the back side of the supports), and you need to put something back where the center supports were or the headliner will droop.

It ain't that hard, and I like the extra stash space up front for road trips. Eventually I will have a switch panel up there for side/rear lights, a front led bar, compressor, etc.

Pictures to explain, and a link from amazon:

Insulation work!

We had Fiberine glass in 1/2 inch osb on the ceiling and 1x6s down the sides so we would have some anchor points.

Started with Noico red in the nose, and glued up some 1/4 closed cell foam reflective insulation over that.

On the sides I went with 1/2" rigid styrofoam, a layer of the 1/4 closed cell stuff, and another layer of 1/2" styrofoam between the uprights for the siding. I will close all that off with plastic sheet (vapor barrier) before I run the wiring and hang the siding.

For the top I'm just using 1/2" styrofoam, 1 layer of 1/4 closed cell foam, vapor barrier, and 1/8" plywood sheeting.

There is a bit of rock wool invloved in some corners and crevices, and 1x2 stringers to hang everything on, but that's about it so far.
