It's quieter in the cab than my 62 p/u with a small block 400. I think it also quieter than the old 6cyl with turbo mufflers that came out of the suburban. Right now I don't even have a firewall pad. I'll add the firewall pad and something under the rubber floor mat in the future. I do have a dB meter that I could take some readings on to have a real comparison between a few vehicles. You can definitely have a conversation with the passenger. It seems like the diesels avoid some of the noise due to the lower rpm that they run.
