I believe the OP is wanting a TOTAL Electric Motorhome. That means it will use Locomotive type propulsion going down the road. NOT EVEN FEASABLE, at least in the next 10 to 20 years. You MUST have a large Locomotive type Diesel engine to run the Propulsion system, yet, that part would be extremely large and heavy and you have to figure a way to transmit that power to the Electric traction drive to move down the road. Remember,RV motorhomes weigh 26k to 32k pounds, NOT 5k like a Tesla. You LIVE in them and transport your belongings and there is not much extra space for a battery type propulsion system. Doug
