Couple ideas, pull the batteries, what is the age of the batteries, check water level and put them on an ordinary battery charger. Overnight or so. See if you can get them tested or check the voltage a while after charging. A hydrometer can be a good tool to check battery health too. I'm also wondering if there is a way to disconnect the convertor from AC power and just hook up a good 30A or so battery charger for a test run.

I wonder if your convertor and/or batteries are done.

Electrical armchair diagnostics has it's limits, proceed at your discretion and comfort level.

I think the 30amp fuses are converting shore power to all devices that run off the battery, including the battery itself. I think something in the converter is failing, and vibrations during travel either make it work or not.

Since the refrigerator no longer switches from gas to electric automatically, and since I canít seem to find a ďsmoking gunĒ, I have decided to take it to an RV repair place Iíve used before. We have some long trips planned far from home and this situation is too unstable. Iíll share the results when I get them for future reference.

No battery power

I had the same problem for a year. I removed the post connections scrubbed them with a wire brush added some dialectic grease. Never have had a issue again.

Thanks for the tip. The trailer is in the shop, so if it’s a battery connection problem, I will be summarily embarrassed...
