Also, if you post a question on a specific item or appliance, I'm sure someone can tell you how to operate it. All the appliances (stove, refrigerator, hot water heater) were purchased from a 3rd party manufacturer by the maker of your coach. Other RV manufacturers also purchase the same appliances from the same 3rd parties.
