Unplug your rv from the shore power. Make sure the inverter is turned on. With a test light or small lamp, go around and check all the 110 plug ins. The ones that have 110 or make the lamp work, are on your inverter. Most likely, it is only the ones that your tv and dvd player are plugged in to. Some rvs have larger inverters, and may have other plugs that will operate off the inverter. It would be good to know how large your inverter is. This will tell you what it is capable of running. A kettle for example would take around 1400 watts. A 1000 watt inverter would be too small. My friends National rv has a 3500 watt inverter, and almost every plug in it is on the inverter. If you have your original build sheet, it might list it. Cheers.
