Most of the topics under Maintenance, Mechanical or General Discussion will be of help to you. Just depends if you run into any issues.
Be wary of letting the dealer or a shop change your oil: many horror stories of them using the wrong weight of oil or a non Dexos2 oil for those vehicles under warranty.
Change your differential fluids sooner than later: wish I had done both before 40k miles, they were disgusting. Change the transfer case and transmission fluid (and filter) around 40-50k mikes or sooner if your truck is shifting hard or funny.
Make sure to drive at least one long drive of 30 minutes or more at 40+ mph a week to get the DPF up to temp long enough to do a regen cycle. The longer the trips at higher speeds you do, the happier the truck will be. Short commutes of 15 minutes or less at city speeds will cause problems.
Would highly recommend an oil catch can. There are a few articles on here about this to explain why you need it, just search for them.
Use a diesel fuel additive of good quality. I know our engines are made to run on Ultra Low Sulfur Diesel but I still believe it’s hard on parts internally. Something that adds lubrication (and cetane but that’s a bonus) is good. Something like Stanadyne, JD Fuel Protect, AMSOIL Injector Clean + Cetane Boost or Opti-Lube XPD. If you live in a cold climate, consider getting an Anti-Gel from any of those companies as well.
