most of the appliances will have their own ignition, the
propane will need to be turned on, and the individual appliances may or may not have pilots or auto
light circuits.
most likely you will need a
battery on board in order to make anything function (house
Battery 12 volt). look for a model number for each appliance and do a web search, most manufacturers keep manuals and troubleshooting guides on their website.
Welcome to camping and our little
fiberglass RV group. While our trailers are substantially different, the appliances are not so different and we will be glad to offer suggestions where we can.
