Holy smokes! Whatever you are doing now, STOP, order the Dynamat and insulate your doghouse.
Finally went for a ride in the RV today and the reduction in the noise level was amazing. I was going 70mph on the highway and didn't even realize it as I was able to have a conversation with my wife without having to shout.
A much more pleasant driving experience.
On a technical note, the iphone app really did not show much reduction in db. Not sure why that is the case.
As others have stated, it is unbelievable that the factory does not add this insulation.
