Treelog,
I am as we speak, sitting in Fabick Cat in Joplin, MO having the 60K service done. Fabick was involved closely with Newell when Cats were being used and the recommendation from the service manager was to do an upper service (valve lash, jake, and injectors at 60K. It makes sense as apart from the normal break-in wear, coaches can take quite awhile to reach the 60,000 mile mark. In my case it took from the 2007 (build date to 2018) to reach that high. While that is being done, I am also doing a flash to the ECU with the most up to date program and having the fuel line check valve replaced along with a fuel pressure check. I do admit to being "old school" meaning adjustments are viewed as necessary and a normal part of the maintenance cycle.
In speaking with the mechanic, most of the adjustments were fairly moderate in scope. Meaning, all of the components needed some adjustment but none were of an amount that should be of concern.
The downside is my floor hatch took all day yesterday to get out at the factory. Turns out someone decided to screw down half of the panel in an area covered with tile. Looks like 4 or 5 tiles will need replacing. Ugh.. But thats not really surprising as many people have reported problems with the original install.
The good thing about doing this now is I will make sure that the hatch will be easily removable the next time.
Something to think about, if your not doing this service interval which the factory is recommending, because of the problems you most likely will encounter removing the floor I think you will going down a risky path, its my experience most repairs on my coach involves undoing or redoing the components involved due to some less than optimal design or install. Your engine is also more complicated then my 2006 version so the ECU upgrade could be of some real value.
Best of luck.
