This RV by design has no built in generator.  Everything is powered on the deep cycle battery in the RV except for high-wattage appliances (e.g. air conditioner and microwave). There is an A/C, but if you want A/C you'll have to find power elsewhere on your own.  There is no hot water.  If you use the furnace the furnace fan consumes the battery quickly so be prepared to recharge, e.g. plug-in, generator or solar elsewhere, or bring extra batteries. I may help with extra batteries.
