Dodge has placed top 3 because the Dodge Cummins is the best diesel on the market currently. The Cummins is Dodges diesel. The reason I have not chosen to place Dodge in the top 2 is because although their diesel is the best, their gas trucks probably rank fourth. The Cummins can by far out haul, tow, and carry other diesels out right now. Whereas the gas still has good fuel economy, but cannot quite pull as much as a Chevy or GMC.
