You have the same inverter that is installed on the Challenger. There are two issues which are:

The size of the inverter cannot handle everything in the coach. Thor has wired the coach so that only the refrigerator and television circuits are wired into the inverter. The justification for this, IMO, are the refrigerator needs power to stay cool when disconnected from shore power and the generator is not running and the televisions may be required for passengers while running down the road.

Second, the inverter is modified sine wave and some items require pure sine wave and not modified sine wave. Devices that tell time (eg digital clocks) or regulate heat (eg coffee pot, toaster, electric blanket) will generally require a pure sine wave inverter.

Hope this helps.
