Most coaches aren't wired so the Inverter can power any circuit. They typically don't have enough space to house enough battery power. Some of the higher end Class A's and the higher end Super C's can have enough battery and inverter power to be wired this way from the factory.
The typical Thor coach with an inverter is only wired so a few outlets are powered by the Inverter. This includes powering a residential fridge, a TV and maybe another outlet in the bedroom for a CPAP machine.
As others have suggested, download the schematics for your coach from the Thor Owner site and it will show you which outlets are on the inverter circuit for your specific coach.
I did a lithium conversion about 18 months ago. I installed (5) 170AH LiFePO4 batteries from BigBattery to give me 850Ah. I then upgraded the stock Xantrex Freedom X 2000 Inverter to the Freedom XC Pro 3000 Inverter / Charger to give me plenty of power to run one of my two A/C units or the convection oven / microwave.
I took the output of the inverter and used 10/3 wire and installed a 75A Subpanel (something Thor should do as recommended by Xantrex but doesn't). I left the original inverter circuit intact but added a 15A breaker for the out put to the fridge, TV, etc. I then used 12/4 SOOW wired and did a run from the subpanel to the WFCO Power Center. I had two open circuit breaker slots (one for each line of my 50A service) so I installed a 20A breaker on Line 1 and another on Line 2. I connected one hot wire of the 12/4 SOOW to breaker 1 and another hot wire to breaker 2 and the neutral and grounds to the busbar in the Power Center.
When I want the inverter to power every circuit, I turn off the 50A main breakers and the 15A breaker for the inverter input so I don't back-feed my EMS and ATS and don't back-feed the inverter. I then turn on the two 20A breakers so the output of the inverter back-feeds the Power Center.
When I am ready to switch back to shore / generator power, I turn off the two 20A breakers and then turn on the 50A mains and 15A inverter input breaker.
