This is just loose tough that I had researching solar panels for my house.
Solar companies hardwire the system to utility power line and seal all the boxes. You have to draw your power from the street line and only tricky math gives you some discount for having panels on your roof.
I ask saleswoman if in case of emergency I could tap into system and use the solar power directly. She never heard about it.
Same can be with more and more common electric cars.
Would manufacturer make those batteries easy removable, I bet lot of big RV owners would run to buy electric cars and use the batteries in RV, while leaving the car at home.
Toading electric car and wiring it batteries to coach might be the option too.
Than you cover your RV with solar panels and not only you power AC for no additional cost, but the reserve charge will let you drive the car to the city for no extra charge.
At home your recharge your commuter from RV -without plugin into house power (assuming you are home at daylight)
Just dreaming. I know "for liability reason" that ain't going to happen.
