What's the source of the road noise at highway speeds?
Is it the vents on the rear of the cab?
A poor insulation factor?
Anyone have success in eliminating/reducing the noise?
Ideas?

My father in-law sprayed the whole underside of his 3500 with rubberized under coating & he said it made a big difference...killed a lot of the road noise
