don't believe anything the generic FR owner's manual says.
it is a basic manual that just goes over basic RV systems and almost never has anything specific to your model.
inverters are almost always an option and installed as an aftermarket item.
the Sunseeker home page doesn't show an inverter as a standard feature, nor does it list as an option.
it only shows a converter, which virtually all RV's come with.
