Puzzler for you electrical gurus....
A year ago I bought a 12v LED light strip (18" long) and mounted in the van I use an another RV. I like it so much I bought a couple more of them to use to mount in my Bigfoot pictured below. These ...

Maybe the inverter is putting out some AC. I don't know how much it would take to make it not work but you can test it by putting the voltmeter on AC.
That's what I suspect. The converter is putting out a "noisy" 12v.
Put your Digital VOM on an AC scale and measure the 12v when shore power is plugged in, to see how much ripple is coming from the converter. Just for grins I measured mine, and was seeing about 50 millivolts of AC on the 12v from the converter. Voltage is stable on a D.C. scale. I don't have any LED lights in my camper though.
If I remember right, D.C. ripple is an indication of a bad capacitor. On the ancient stuff I used to work on, we'd tighten all the capacitor screws on the power supplies and look for bulging or leaking caps. Those caps were huge and were screwed on, yours are much smaller and will be soldered.
