Nope. Fridge woulda been on. Whatever the radio draws and probably the CO detector. Smoke detector is 9V battery. The screenshot is what the camper battery is seeing. The charge voltage is more than the battery voltage, so those other devices are running off the truck, at the time of the screenshot.

An interstate multi-use crap that came with the camper in parallel with an older 100AH-ish deep cycle 12v that came out of dad's fishing boat (trolling motor). Certainly nothing special. Can't wait to get my 420AH, 6V, L16s... Anyway, yeah, junker batteries, basically.

No idea. I'd have had the lights on, so it would be the GM's "bumped voltage" mode. Voltage drop could be calculated, I suppose.
I didn't mean to hijack, just trying to show some real world (as in, I saw it and measured it and documented it) charging rates. People often say "it's just a trickle", but I'm saying it's X amps (or can be). I don't even know the charge rate of the converter at a similar battery voltage.
