Some have tried it but the one I'm aware of sold their Escape and bought motorized unit. It had extra batteries, not sure about the propane but it was a one of a kind unit which I do not think Escapee's would make again. You may have to purchase a stock unit and then replace the propane stove and heater with electric. Also the refer runs off propane while towing, so additional solar and batteries would be needed.
