2019 Ram Cummins, Manual Regen?

Rant video. Why isn't the mainstream truck reviewers asking the hard questions? Example: 1.What is different with the emissions systems for the 2019 and 2020 models? 2. Is regeneration still an in cylinder design? 3. Are there new materials used for the DOC/DPF and SCR? 4. Is there less EGR pumped into the engine? 5. Has regeneration times been reduced? 6. Has regeneration been more refined and more seamless? 7. Is there a manual regen option for the Rams? These are just some of the questions I wish the mainstream truck channels would ask. Everyone is going to talk power, towing and so forth, but what about emissions and maintenance?
