I would not assume that the 7 pin connection is providing charge or adequate charge. Get a voltmeter and check. Even if charging, some trucks have an undersized charge wire. This causes loss and therefore may not provide adequate charge.
Wiring diagram/reading
I have old absorption fridge, and have wired the trailer so the only power supplied to 12V side of fridge is from the 7 pin. And that is the only demand on charge circuit.
We only camp with power, the fridge runs 120 at camp, 12V when we travel. But you are right, need to know getting adequate power. Could there be a phone app to watch voltage of trailer battery and fridge temp?
