One thing I found out it that they don’t exempt emergency vehicles from the DEF/missions requirements. So one mistake or electrical fault could cause a ambulance, fire truck,etc to to derate and loose engine power en route to a call.
Hopefully come Jan 21 the EPAs days will short lived.

We have had several instances when it was running fine one minute, then flashes up “pull over immediately” and it just quits. No restart, nothing. Fortunately not with a critical patient in the back -yet-. The day will come though.
