I also have a 06 Cummins and the Chevy is a MUCH MUCH better truck.
Please explain?? I'm thinking of trading my '02 Cummins for a '03-'06 Cummins.
TurboIndian has a higher mileage '06 LBZ that he uses for a hot-shot truck for his hauling business, maybe he'll chime in. I know he's had many more issues with it compared to what has been discussed in this thread so far...
