Charging Strategy, 1994 RoadTrek, Part 2 (shore power split)

I forget, do you already have the inverter? And if so is the reason you want to plug the shore cable in to the inverter when no power is available is to make all your interior AC outlets usable on inverter power?

Your plan should work, but do you have the charger yet? If not I would recommend getting a progressive dynamics 9280 3 stage converter. It is an 80 amp unit and progressive units are high quality and made in the USA.
