You may want to ensure that you don't already have a battery disconnect switch somewhere. If you go to the Forest River Windjammer site it says the switch is standard equipment for their new models. I have a friend who has a '12 Windjammer and it has the battery disconnect switch. It may be stuck away somewhere.
