I guess you Chevy guys are right. Better buy the Chevy because they will need the warranty. My Cummins has 242,000 miles on it and hasn't ever been touched. Just oil and fuel filter changes.
Sorry guys I just had to take a little poke at you!
The story about Dodge using the Mercedes engine is old. That was back when Daimler first bought them.
I just can't believe that one of the big 3 haven't used a Caterpillar engine. I think that would be a big selling point. More so than the Navistar.
