So, what has changed over the previous gen trucks to allow this?

Software!

I would also bet the DEF usage is increased. This seems to be true with the L5P vs the LML Duramax

This is what I've seen also.

Larger rear differential and updated AISIN trans.

And updated driveshafts front and rear.

Yes, but that doesn’t add HP/TQ to the engine! Everything down from the engine is after they added more power.

I’ll take one....and I promise not to bitsch about it like some people.....lol!

Are you doing repeated hill starts in forward and reverse at MAX GVWR?

No, but how many hill starts can the new drive-line handle versus mine? At what point will mine break? At what point will the new one break? Which part is the weakest link? If you don't know these answers with 100% certainty, then you are just guessing the same as everyone else.

Between the cattle trailers, RV, goose-neck loaded with hay or tractor, I am probably putting this drive-line through more stress than most. You would think that something would have broken by know with the 1,000+ lb-ft I am putting through if there was a weak link somewhere in there. I don't know exactly what the weakest link is, but then again I am not claiming I know what is or isn't the weak link either.

I am just wondering what the weakest link in the drive train is that will break first. Even the strongest drive train has one weak link. :h

Me too. I have been running over 1,000 lb-ft through all the gears for almost 100k now and haven't had anything break. Traded out the trans for a built one not too long ago, but that was by choice.

I think that usually is the driver.

The operator is the weak link. As much as I am looking forward to no nannies between me and all an engine and drivetrain have to offer, I am not sure the general public is. Operating class 8 trucks in a construction application makes that case. Twisted drivelines, broken undercarriage components are the cost of unregulated high hp in challenging conditions.
