I was at a wedding over the weekend and at one point was sat in the front seat of a Caravelle taxi, and while it clonked away like a good un at the back I noticed how much less road and engine noise was coming through the dash than mine, esp lower down. Now I've got silent coat and closed cell foam in the doors and some bits of the floor, and I noticed when I had the glovebox etc out when I was running wires that it has that white cotton wool type wadding stuffed in there. So what else does the Caravelle have in the way of insulation in the dash? Is the bulkhead insulated in some way?
