The Gumbos asked about a converter not an inverter as I read their question. I have no idea what power distribution system is in a 2017 MHC. The Progressive systems in the Montana have an integrated converter. The MHC might have a lesser power distribution system with a separate converter. What brand/model power system is installed?

If the converter is separate, it is usually under the steps behind the passenger side rear wall (which removes easily) of the pass through compartment. There will be a 120V outlet to supply power and cables to the battery and 12V fuse panel.
