I've read a bunch about Dynamat and other noise dampeners/insulators for a front-engine 2003 International and I'm going to pull the trigger on this suff for the interior:
Amazon.com: Noico Liner 37.5 Sqft Heat & Cool Automotive Insulation Pad, Foam Self-adhesive Sound Deadening and Dampening Mat for Cars & Trucks (1/6'' or 157 Mil Sound Deadener): Automotive
And this for the engine compartment:
and this for the floor and internal firewall.
A fair amount of the noise is likely coming from wind.
The driver side window is definitely a culprit. Does anyone know where I can find a wind defector for that window?

I was thinking of hacking something like this:
If not, anyone fabricate one successfully? I made air intakes for the generators by successful forming lexan, but wind deflectors are a little more complicated to get right I understand.
I've written to a number of school bus accessory shops without success...
Any other tips to reducing noise would be awesome!
