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...
My Itasca class A slides will operate with or without the engine running (E-Brake must be set), but I prefer to have the engine running for the additional power that the alternator provides. Also, the last thing I want to do is put a heavy load on my batteries just as I begin camping (or just before I get ready to leave).
