Thanks for the quick replies!
So I have tried Seafoam per the instructions, no help.
Checked altitude settings, its correct
No cummins dealer here but if I ever put her back on the road system, I will take it to cummins if its not fixed by then...
One spark plug was not firing properly, changed that and now it takes a small load (1 of 2 AC units) so thats an improvement!!! But not back to what it used to do!!
