Bad fuel or Bad / dirty injectors
Low fuel light on, left engine running, bought 75 gallons @ I-80 travel plaza, tank full. So when low fuel light is on I still had approximately 25 gallons in tank.
Back on the road and right away RV is missing, blowing blue, black & grey smoke. Runs ok at cruise but give it power and it's smoking. So I limp my way home 75 miles.
Changed fuel filters and I have dark fuel in the filters and some crud. So I guess I have bad fuel. Now what?
Do I drain all 80 / 90 gallons out and put in fresh fuel? Drop the tank and clean it? Or just drive it and make a few filter changes?
Could it be I had bad fuel in the bottom of my tank that got steered up when I added the 75 gallons?
Has anybody dropped their fuel tank and cleaned it, is it a big job?

So I pumped out all fuel from tank and it looked ok. Didn't find any crap in tank. So put fuel back in and drove it. Running better but still smokes when starting out. Re-check fuel filter looks ok.
So do I need to remove and clean my injectors?

Anybody done that? Is there a manual that I can get for a guide to do the job and torque and spects.
I watched a few you tube videos? Is my engine the same as a Cummins 5.9 Dodge?
What do you think? How do I go about this?
