Possible reasons for your good fortune is the gage of your charge line and as yours is a newer trailer the fridge
may be more conservative on its 12V usage?
I think that the reason of my good fortune is in the wire gauge. Gauge 10 is problem free. I recently purchased used 2013 F150 without towing package, it has tow wiring in the cab, but the wire harness from the cab to the rear of the truck misses tow-related wires (charge line and electric brakes). I added wires myself. The (relatively short) inside cab wiring for charge line is done with 12 or maybe even 14AWG wire! I'm almost sure that tow package wiring from the cab to rear is done with the same wire size. Sure it is not enough to power the fridge
and charge the battery
Let's see how it will work, maybe I will have to replace in-cab charge wire with gauge 10 too.
