Diesel Chevy truck with new Duramax engine

We found a 2004 Chevrolet Silverado and other C/K3500 4x4 Crew Cab that has a brand new Duramax 6.6 or 6.5 engine in it. Dealer was not sure...we will have to go look at it.

How are these engines? And is this truck good for hauling a 15K fifth wheel camper?

Carfax report stated, "axles checked." And 8 months later, all tires were replaced. Can this mean that there might have been problems with the axles?

Thanks for your help in advance!

    Oh...yes! That is why the original owner traded it in! Overheating issues!! and that is why they replaced the motor!!

    Thanks for the info! We will look for LLY or LBZ. Where might this info be found?

    I had a 2005 I just sold. It was a good truck with the LLY motor (2004.5 - 2005). There are a lot of issues that can be found with the LLY motor on DieselPlace.com. I would not suggest you buy with the LLY, but if they put the LBZ (2006 - ?) then you will probably be ok. The LLY has over heating issues. I did not have that issue with my truck, but plenty of others have.

    2004 was probably the worst of the Duramax motors. You need to find out what motor it is. Hopefully they installed a later version.
