Electrical problem

I have a 2004 27' Coachman freelander. On my last trip the power to the cabin lights/fridge running off the batteries started flickering or going off. If the RV is running everything works fine, same with the generator on, or plugged in. I have 2 batteries which are fully charged. The converter was humming while plugged in and I heard the converter fan go on when the gen was running. Any thoughts?

When running off RV (alt. charging) or gen (converter) all is good......then suspect batteries.
Converter humming/fan running is due to high load on converter (hm) and heat generated due to high load (fan)

Need to load test those fully charged batteries.
Also test each cell specific gravity....could be shorted cell
How is the water level?

You have a problem with your batteries

Agree, check the batteries. Load test and specific gravity.
