Running trailer from tow vehicle inverter

The purpose of using an inverter would be to boost the rv battery when it becomes low when dry camping, by running the tv and plugging the trailer into the inverter. I do not have a generator. I will be using a 1500w pure sine inverter. The converter in the rv has a smart charging system(Progreessive dynamics)

In other words you want to use your TV as a generator while not towing to power this inverter which in turn would power the trailer's PD converter - correct? So I have to ask - just which PD converter do you have, where is this inverter located in the truck, are the input cables short and of heavy enough gauge to support a heavy current load, is it properly fused, and are you satisfied the truck's electrical system itself has sufficient capacity to power this PD converter under full load? :h
