The price of an oil change on a DP will get enough Dynamat products to make your V10 a whole lot quieter. Having worked with diesel engines much of my career, I know well the potential cost of repairing them. The Dynamat addition has made my V10 quite acceptable.

Yep I did the Dynamat and sound proof material over the top and my noise level was cut in half if not more, the problem with gas motorhomes is not the motor in front its the lack of sound proofing the RV makers don't install to keep it quiet.
