I need a new truck for pulling the mowers. I am trying to choose between the gas and diesel trucks. Which one would you choose? What are the pros and cons? My choices are, in the diesel area, are the Dodge Turbo Cummins and the Chevy 6.5 Turbo diesel. Then in the gas area are the Dodge Magnum V8, Ford 351, and the Chevy 350. What are your favorites and why? Is it also true that diesels last longer than gas engines?
