@JivaDas,
I doubt any are designed specifically for that. If you intend to be stopped at off grid sites for more than a day or three, order or retrofit RV with 500 - 1000 W of solar panels, 1000 - 1500 watt inverter and 200 - 400 Amp Hours of battery storage. Fit the RV with all LED lighting and select low wattage appliances. LP for refrigeration is pretty standard.
That has been adequate for my off-grid cabin.
