I don't really know if the pickups are like the bigger units.
We have a few newer units at work and this regen is a pita. You just never know when the regen will happen and it happens so unexpectedly.
Our units are operating trucks not transporting trucks, so when your out in the field doing a job and the unit decides it's time to regen
Thats it, your done, all systems shut down until the regen is completed. This is very annoying to say the least.
The actual regen process doesn't really take all that long, our units usually only take 20-25mins, usually.
The regen can happen once a month or two. There are a few factors like idle time, travel time.
