A bigger alternator will be a waste of money but getting 13+ V to the batteries will not be a waste of money. My educated guess is that at 12.1 V the fuel shutoff solenoid on the injection pump is not holding the fuel shut off lever all the way open reducing how much power the engine will make. Solve your 12V problems and hopefully your other problems will go away. I would run a string from the fuel solenoid to under the bed so the DW could pull on it if you loose power to make sure the lever is all the way open.
When I had a 8.3 Cummins I carried one of these as they are a know problem item.
