If you want to continue off the grid then you should look at a solar panel setup. With those and some extra batteries a lot of people manage to get by. It requires power management on your part, thinking about how much power a utensil requires and so on. Switching to all LED lighting helps with that since it greatly reduces the load from lights.
My wife is the same and just prefers to use the CG washer and drier. You would definitely only be able to run those on shore power.
The other thing you have to think about is water and wastewater control if you plan to stay off grid for weeks at a time. People use these wastewater totes assuming there is a dump near by.
