OK, please tell me how the emission systems and standards on a Ram 5500 with a 6.7 Cummins and 17,500lbs GVWR and a Freightliner-chassis UPS truck with a 6.7 Cummins and a 17,500lb GVWR differ. Be specific.
Why are you bringing the Ram 5500 into this? How about sticking to your original argument, which was comparing UPS/FedEx trucks to Ram 2500/3500 trucks. The Ram 2500/3500 pickups have EGR and DPF, no DEF or SCR. The Dodge/Ram C&C trucks use DEF and have SCR so even the Ram 3500 pickup and Ram 3500 C&C trucks have different emissions systems.
The UPS and FedEx trucks with the 6.7 use SCR.
So, again, you can't compare the MDTs with the 2500/3500 pickups in terms of emissions systems and how well they work (or don't work) under similar conditions.
