Intermittent parasitic draw

[high mileage]

Guys, I have a draw that happens randomly. Sometimes if I leave the truck parked it'll drain the battery in 2-4 days, other times it'll be fine for a week or more.

New alternator and charge cable, replaced the agm battery twice. I've now done a full parasitic draw test and the only circuit that had mV was the info circuit, which only had 1.8mV.

Am I screwed? What's next here?

Confirm for us that the mV reading was across the fuse test points.

Depending on fuse size, has that reading been converted to A (or mA) using the appropriate Power Probe Fuse Voltage Drop chart? (Estimated draw varies by fuse size and amp rating.)
