The MLV was then added along the top and rear of the dash. It is important that all of the area is covered - noise will get thru the gaps. Decrease in noise was AMAZING ! Engine sounds like it was moved away from you, and now sounds much smoother. Wide-ope-throttle down entrance ramps is now FUN rather than ear-splitting. It was a lot of work, but well worth it to me. But, again, I'm sure a lot of the improvement was the gap around the front of the dash in my coach,which may not be a common issue.
I bought enough MLV to also add under the cab carpet - when I get some more spare time. But, not feeling an urgency to do this, as I'm pretty happy where the coach is now.
Between these noise fixes, the handling work in another post , 2016 type shower curtain, and higher bathroom faucet, I am really getting to like this Vegas !
