Regen Issues
I have a 2017 F250 SD 4X4 with a 6.7 Liter in it. the truck has 145K miles and I idle a lot as I am job sites almost every day and the truck is my office.
My truck regens constantly @ 1000 RPMS and stinks when it does - The truck will regen to to three times in an hour of idle time........
What's wrong or is this normal ?

The factory settings do not allow stationary regens, they must be forced with special software.
Is it really cold where you are at?
The truck will go to high idle in cold weather.

Unless you grew up operating pre emissions tractors like I did, you might not like the diesel exhaust smell

What you're smelling is the DEF which is injected to help the SCR function during high idle. DEF is referred to as "Cows Urine" for a reason.
Nothing out of the norm as far as function for a diesel sitting idle while you work in the cab.

For anyone who idles their truck a lot, the high idle should be set up and used any time prolonged idling takes place.
Idling any ICE engine at low rpm for extended periods is bad for them, and is especially so for emissions regulated engines.
Way back when I drove 18 wheelers and we idled overnight, we always set a high idle speed.

that smell is not the DEF. It is the DPF. My excavator does this in re-burns/idling. It does not have DEF on it! The smell is kinda a sweetish smell. My trucks do it sometimes as well.

Takes a very long time to use up DEF in my '20. Even with stop and go non-highway driving. Last time I filled up with DEF the gauge said that I was good for 6K miles. So, not unusual.
