Can the drivers and passengers hear the clatter of engine noise while driving down the highway? I am talking about the older diesels, the ones that sound like a Briggs & Stratton engine with the muff...

Depends on your definition of older model. I had a modified 96' Dodge Cummins. When pulling a load up the hill my wife learned not to talk to me. My 2006 Dodge Cummins is alot quieter with a heavier load.
