In my 2016, the outlet to the right of the passenger is powered by the inverter as well as all outlets that a TV is plugged into, plus the outlet in the loft - where an 'optional' tv could be connected. There's a secret outlet behind the fridge also.
Before the modification; the 2 outlets above the dinette, on both sides of the bed required shore power. Now they work off the inverter as well.
I purposely did NOT connect the GFI outlets (above the sink, at the entrance door panel, in the bathroom) to the inverter.
There are a couple outlets outside. I doubt they are powered on the inverter but I never checked and rarely (maybe never?) use them.
It's interesting that everything I fix on my Thor is easily fixed better than new - and I'm no craftsman!
