Loss of power, misfiring, then dpf full

I'm getting random loss of engine power (especially on hills) and in higher gears occasional misfiring on my t680 with 400k miles. Google yields others having this caused by various things from simple senser/wiring issues to the ECM itself. Been happening the past few days and slowly getting worse.

Thought I could finish my load and put my truck in the shop (fortunately a half mile from the final) but now 110 miles away I suddenly have a dpf full warning and a much bigger derate. Already driven 7 hours today so it should have cleaned while driving, right? Really debating if I should believe that it's full givin the existing engine problem. Maybe a false reading if the ECM is bad.

What would the rest of you do? Limp the 110 miles to a shop at 30mph (at 2am so no traffic) or call a tow truck?

 

Check engine light was on prior to the dpf full alert, but dashboard says "no warnings or faults".

Also seen some people with the random power loss and misfiring saying their engine light was also on but hooking up to a computer reported no error codes.

 

Nope

Did try letting it go for half an hour with the rpm manually bumped up to 1400 with no effect, but don't know if that even has the same effect as an actual parked regen.

 

Yea, I know the process, but holding the button even for a minute doesn't initiate it. RPM just stays at low idle. It should start after holding the button for 5 seconds, has every time I've had to do a parked regen while taking a 34 (truck doesn't do them automatically it just pops up a message saying a parked regen is needed).
