Some good points explained clearly here. Modern diesels have come so far that alot of preconceptions and myths are still out there about them. So many people make the blanket statement, "diesels cost so much more to maintain..." When this isn't always the case. It boggles my mind why people still tow 7k+++lb trailers with gas trucks. I love gasoline engines. I have raced several of them. My wife's last two daily driven cars have had over 350whp and run high 11s in the quarter. But that being said, I would never choose to tow with a gasoline vehicle. Once you buy a reliable(Cummins) modern diesel and live with it for several years you learn to appreciate them.
