I have a friend who just bout a new Winnebago Class C. He said in order to put the slide out the ignition has to be on or the engine has to be running? I did not question it because I have never had...
But WHY the difference? I have seen a 42 foot Toy Hauler with 5 slides and two house batteries run the slides in and out when dry camping on the batteries alone no 110 volt and no generator....
It appears on the Motorhome that you have no choice the engine has to be running...
