Forest,

I removed (it was falling off) the insulation from the front door panel and installed some of Gordon's aluminum/foam/vinyl/foam material to the entire door. I sealed the edges of the foam with the aluminum foil tape. I placed an additional foam rubber seal on top of the existing seal around the entire perimeter of the door. I am in the process of fabricating a piece to seal the 2 by 2 channel where the cylinder is. An amazing amount of air and sound exits that hole.

Also he demonstrated to me how much sound the blower makes on the passenger side by temporarily placing some of the acoustic barrier material in front of the fan, but not closing off the louvers or course.

Correct, the air bags attenuated the vibration but do nothing for noise. The vibrations made it hard for me to sleep with the gennie running. My gear head brain would register the slight change in vibration normal with the gennie loading and unloading as something just went wrong. That would wake me up many times during the night.
