There may be an inverter. Both Bs I've had had small inverters of 450 and 700 watts just to run the TV in a dry camping situation yet little was said about them in the literature. In our Pleasure-way Plateau it was concealed in a cabinet you could not easily get to, yet it was there with two AC plug outlets. In our GWVan Legend the outlets are accessible along with a USB plug in. I'd guess if you have a converter electrical system set up and you can watch TV dry camping you most likely have that inverter.
