We're winding down on the interior of the camper truck.....pretty happy with where we ended up. I'm going to experiment with a different firewall pad. I installed some of the Heat Wave Pro which is nice stuff but then I remembered I had some Thermozite material from the Troopy's headliner. Impressive stuff. So we did a test on part of the firewall with each of the product and I think we'll do the Thermozite.
This is the Heat Wave Pro...

Got the rear done....went with tan subwoofer material for the back wall. Looks really good.
Also put in the closed cell foam decoupler...a little embarrassed by my half ass install but it's in the right place...just looks bad. Good news is, nobody will see it when the panels go on

Your sound/thermal insulation projects often remind me of pictures of the panels and bulkheads in Apollo-era spacecraft...
