Welcome to the 14 -19 Ecodiesel & our forum.
Some have the philosophy of being proactive to avert potential problems and work towards long trouble free operation. Others worry about protecting warranty and hope the motor expires before the warranty does. I believe in investing in your truck for problem free operation & long life.
1. Engine & trans tune. Fix the AEM government detune. GDE used, (closes EGR valve) GDE new gov compliant, Sofa King, HD Diesel, MR Tuning, Celtic several to choose from.

2. Check if EGR cooler has been replaced under warranty. If not either get it replaced via warranty if possible or search for good EGR cooler delete kit. In the mean time watch coolant level as you want to keep it to the seem or above. All the factory original EGR coolers leak eventually. https://noecodelete.com/shop/
3. With this truck its easy to change your own oil. But regardless every 10k get it done with a 10k rated filter and an approved oil such as Rotella T6. Even if you are buying the oil & filter and paying a local to have it changed. Rockauto is a good mail order source for oil fuel & air filters. 2014 RAM 1500 3.0L V6 DIESEL Turbocharged Parts | RockAuto
4. Replace fuel filter/water separator with the factory Mopar filter. This is another one easy to do yourself. Tips use a large zip lock bag or wide mouth coffee can to drop the old filter into so that you don't spill diesel on yourself. When finished key the ignition on and wait for the pump to quit running before trying to start. This gets the fuel from the tank up front to the high pressure pump. I do it every third oil change or 30k per my original warranty.
Every spring & fall I pull the rubber fill plug dip my finger in and check the rear differential fluid. If its silver with wear metals or brown with water rust change asap. It should be almost clear. 2.5 quarts of 75/140 full synthetic differential fluid plus if you have a limited slip get a small bottle limited slip additive or fluid that contains it. Walmart has the differential fluid 11.94 a quart plus the additive. If not most auto parts stores do. There is a drain plug on the bottom passenger side think it needs a T40. Simple do it yourself job.
Every 100k I change the transmission fluid. Easiest done with a shop lift so perhaps a local shop. You can get a new filterpan online very reasonably. Valvoline Max life full synthetic transmission fluid by the gallon at Autozone is inexpensive and has worked for me. Just bring the filterpan & fluid to your local shop. As to front differential & transfer case sheesh maybe every 150 or 200k. 785,000 miles this is what has worked for me.
All of this simple maintenance stuff you can do yourself or have a local mech do. You don't need to pay dealership service prices for it. If you have a check engine or warranty light a simple inexpensive two button code reader such as the Bosch 1000 will tell you the code (you can internet search the code) and can clear basic codes. It can also get you out of limp mode so that you don't need a tow and can deal with the problem on your own time. Enjoy the truck and our forum let us know your experiences. This is a basic list feel free to add to it.
