I have attached a photo of where the Inverter control (it's called a "remote" by Magnum, the manufacturer) is located. It's circled. If you don't have this remote then you very likely do not have an inverter.
Also, there are photos of it and the inverter and the inverter's location in the Operator's Manual, which it sounds like you did not receive with your coach. So, here's a link to that all important and huge resource:
Getting the manuals passed a long may be due to the way they are treated as "excess" baggage. Used RV dealers seem to be a somewhat "willfully ignorant" group when questions are asked, so getting rid of any extra info is one way to avoid slowing down their day!
Also I have found several where the handy spot to get the info out of the way is the space under the dash AC unit where it catches the condensation drips!
