Two things come to mind. I have no interest in pushing it. They need to think of something to remedy this. One of the great things about motorhomes is the lack of need to set up. I can just turn off the engine. Get out and turn on the gas and I am good to go. Whilst its great to get 730kms. Wonderful for the pocket and would make travel a lot more viable for some. Does this mean you arrive with your batteries empty and no power to run all your amenities when you get there? Perhaps like a current MH the house batteries are charged from the main car charge going along.
