I had the same problem. It was my battery charger with a bad "Crest Factor" . It was a Mastervolt 24V 50A charger. It was on a 6A shore power connection that blew after a couple of minutes. The charger drew pulses of 10A only in the peak of the sinus wave.
AC current clamp meters are pretty cheap, I'd start going through the circuits. As you say the fact that the breaker blows faster the second time suggests a high constant load rather than momentary. However, it might be, for example, an AC or refrigeration compressor starting up and providing the straw that breaks the camel's back.
You said, "Turning down the Current Limiter to 10 Amps, does *NOT* fix the problem". But then you claim you are tripping a 16 Amp Circuit Breaker. These two sentences cannot both be true. Someone needs to actually measure the Amps and provide some truth.
Current limiter set to 10 amps for the inverter draw. There are still other DC loads. Yes, someone need to measure amps; perhaps the owner can and report back here.

Perhaps using a thermal camera might help isolate the problem?
I had an RV that had a gas fridge that would switch to 110 v after 2 minutes
