Thanks - I appreciate the responses and help thinking this thru. I'll call Progressive for a calibration procedure.
I agree there's a poor neutral somewhere that's the culprit. The electrician is a local small town guy and may not be a master. Nice enough guy but a bit defensive of his prior work "cleaning-up" the system. I need to up my skill to help trouble shoot the open / bad neutral.
troubleshooting the source of the issue . . .
If I connect to 20 or 30A, I should see equal voltage on the Progressive display correct? (20A & 30A having a single load that's shared by the 2 loads on my 50A trailer)
Make sure the poor neutral isn't your cord. Measure both legs at the pedistal and then hook up and measure both in your panel.
With a dog bone on 20 or 30A, yes both sides should match or your unit needs calibrated.
