The best was an early/mid-90's Pete cabover that had a "front" with the slightest V-shape to it. Subtle.

I used to own one of these things. Amazingly smooth ride, came from the factory with a Blaupunkt stereo system, and I averaged 9mpg with it, over varied terrain with varied loads. The real killer, and the reason I sold it, had more to do with parts availability from Peterbilt, as they didn't make 'em for long, and quickly declared 'em obsolete.
I kinda miss that ol' truck, though.
