Updated: 6/29/16 - Watch and listen to a short video that compares three areas of the EV with different states of insulation/sound deadening (rear hatchback with FatMat & denim, read driver's side panel with FatMat only, and middle panel area with table with nothing)
My 1993 Eurovan Weekender is a bit noisy while driving (ambient and road noise). There have been a variety of reasons for this including bad shocks, missing window molding, misc rattles inside, etc.
So I've had a constant goal to make it more comfortable and quieter. This past weekend I did more FatMat in the front passenger door and denim insulation in the sliding door and rear hatchback door. The removal of the panels from the doors is relatively easy, especially if you've done it before. In addition to the sound dampening, I expect some better insulation for maintaining a comfortable temperature while camping/sleeping and even driving.
Next up, I intend to figure out how to remove the interior panels along the driver's side near the table to the rear and other back panel as well.
Here are a couple of photos.
