Cattleman friend bought a new 3500 four door Dodge diesel. Dash board lights kept coming on. He kept taking it back. Finally it "lit up like a Christmas tree" and shut down. He had it towed, got rid of it (Lemon Law I bet), got an F-350 Ford with the big gas engine and is happy. Put his aluminum bed on it, says it gives 13 mpg, doesn't leave him stranded. Says power is good, no problems pulling a loaded Gooseneck trailer.
I've seen farmers who loved their diesels, going with gassers due to all the EPA stuff. Older diesel trucks bring a premium and for a reason.
