I guess I am not what your guys would call a real diesel purist because I have never liked the sound of a diesel engine, liked the power, the economy and the reliability, but the engine's "voice" always left me a little flat. I had a 2nd generation Cummins that I liked very well, then I lost my mind and traded it in for 3/4 ton V-10. When I heard, and then test drove, my first 3rd generation Cummins, I thought that this was a diesel that I could be happy living with, had all I wanted in a diesel, and it sounded good. Well, today I drove my friend's new Ford 3/4 ton 4X4, long bed, crew cab, Laredo 6. 0 diesel and his in cab noise level was less than my new 3500 4X4 Laramie, and less than another 03 2500 Dodge SLT, 5. 9, that I drive once in awhile. I don't believe that my buddy's truck has a much power off the line, compared to mine, but his is an automatic and mine is a 6 speed. But it is quiet. Sitting next to each other, they both sounded about the same, the Cummins might have been a little more quiet. But inside, his had the edge. I would guess that Ford must have used more or better sound absorbing material. Have any of your other guys driven a new 6. 0 Ford diesel? Did you have the same experience? I am a long way from switching, but I was much more impressed than I thought I was going to be.
