2019 Avalanche 333 NK solar plug in ??

[Jacko]

I have a 2019 Avalanche 333MK and does anyone know if you plug in a solar panel and control unit to the solar ready plug on the side near the front battery box, what batteries does it charge? I have one battery for the slides and jacks, on the entry door side and 2 batteries for the inverter for the residential fridge, located in the large storage area under the front bedroom. TIA

Typically, the wiring from the plug to the "controller area" is one part of the "Keystone Solar Package". The other part is two wires that "go to the area of the battery boxes and are not connected at either end"...

I'd guess your batteries for the coach AND for the inverter for the refrigerator are "co-located in the same place"... If so, then it would be your choice where to connect those "solar cables" while you're installing and connecting the rest of the solar system.
