Hi Is anyone having problems with the crank breaking, this truck only had 68K on it and was not abused at all? Any insight is appreciated. I have been off sight for a long time so I have not read any posts.

Yes, it's a known problem on the 6.7
It's root cause is it's Low Mass design crank. It is utilized because it aids in lowering acceleration emissions. It also makes the wind up quicker.
This design has the draw back of it being vulnerable to lugging snapping.
Some snap without lugging the engine, even no trailer.
