This is the A-Pillar on the passenger side (rotated 90 degs). If you pull back the plastic covering you will see daylight. That is because Thor did not properly seal between the plywood and the engine compartment. I saw this while installing reading lamps in the cockpit.
This is the view of the A-Pillar from the engine compartment. The yellow foam is what I added. The gray foam was what Thor added. As you can see the gray foam is hardly useful. After adding the foam it made a huge difference in noise. BTW also look at your mudroom There was a 1 1/2" gap between the mudroom floor and the wall where the mudroom sliding door is mounted. I could see straight down to the road. I foamed that as well. All this helped a lot with heating and cooling as well.
