A B10 number is the design life of the engine. It is a number that supposedly 10% of the engines will have an engine internal breakdown in this number of miles. The B50 or 50% is usually not a huge amount after this number.
The number is higher on the duramax because it has a 20k mile longer design life. The idea that a diesel engine lasts forever hold some truck for a class 8 tractor or a locomotive or a diesel ship but for a pickup it doesn't hold water. Even lots of medium duty truck are running around with 300-350k design life engines. I believe the powerstroke is very similar design life to the duramax. The cummins in the ram may be longer, I know it is longer for the version of the engine that goes in the medium duty trucks but the one in the pickup has a hotter tune and may very well be a shorter life.
