I don't have an image of the contents - but there's generally 6 breakers in addition to the 12 volt fuses. There's also fuses in the panel to the left of the first step in the stepwell in our 2250; I suspect yours is similar. The fuses are for 12 volt items, so these won't help in your case.
On our old motorhome, some 110V outlets were connected to the microwave circuit. The circuit with the GFCI controlled the remainder.
