Mercedes and Detroit build some of the best engines in the world, BUT, none of them that I am aware of are sized right AND EPA certified for use in a light duty pickup. The Merc's and Detroits used by Freightliner and Sterling would crush the front end of a one ton. Be ready for the '07 Dodge Commercial line, they will have the Merc as an option alongside the larger bore Cummins, as well as a gas option. And for the last freakin' time- please tell all the "stupid" people to stop saying that Ford owns Cummins, etc. , etc. , etc. Instead of repeating what some high school dropout told you, do some research for yourself. It's all public record. Ford owned some stock as an investment, they sold it, they made money. That's what companies do with their money- they invest it to make more. Business 101. Dodge renewed thier contract till 2010 with Cummins. Far enough out for now considering the "daily" changes regarding diesel emissions. Ford has indeed invested millions on their power strokes, and yet, you can still buy an ISB in your new F650/750 (at least the last time I checked). Ford BELIEVES in their power stroke (don't really know why), and they like it! International LOVES that engine and it does VERY, VERY well for them. No more Ford owns anything talk- it gives me gas!
