I just got a new to me 2022 Durango 301RL. It has a 50 amp distribution panel and I noticed a 30 amp subpanel in the basement area. The subpanel has it's own 30A breaker on the main panel. What's the purpose of the 30A subpanel? Thanks.

Does it have the solar package? If so I'm pretty sure that is what it's far. If I remember correctly that is to keep your 110 plugs hot when not plugged into shore power. If I'm wrong I'm sure someone will correct me.

Okay, I think I figured it out.
The best I can figure, it's running like this:
The 50A shore power comes in to the WFCO main distribution panel in the rig. That panel powers the AC, Fireplace, microwave, W/D and converter/charger. That panel also has a 30A breaker labeled "sub panel" that goes to the Xantrex Inverter. From the inverter, it goes to a sub panel that powers the GFCI outlets in the rig.
If you have shore power, the inverter is just a pass through. It takes the 30A power from the main WFCO distribution panel, passes through the inverter to the subpanel and on to the GFCI outlets.
If you don't have shore power, the inverter draws power from the solar charged battery(s) and supplies that power, through the subpanel, to the GFCI outlets. You wont have power to the AC loads that are supplied by the main WFCO distribution panel (microwave, fireplace, AC, etc.). You'll only get power to the GFCI outlets connected to the subpanel/inverter.
