You can clamp that meter around any wire in the RV without worry.
I am betting it is right close to 500 milliamps. (one-half amp)
Not sure how accurate that meter is at such a low reading.
Use the 40 amp DC scale.
Yes, I got about 0.6a when I tested the 6 cf frig in the earlier trailer. That was when it was actually firing, you could hear the propane burning. Not sure what it was otherwise, but with the hot water heater, it was 0.7a when firing, and only 0.1a when off.
You can do these measurements with other stuff on, as long as their current draw is constant. Measure the baseline current, then turn on the frig and measure the current again, subtract the baseline.
My batts also have some small self-discharge, baseline current that you can measure when everything is off. But then there are four of them and they're flooded. The OP's agm should be a lot less, not measurable.
