I finally got around to figuring this out. My inverter is behind a panel in the large rear storage area. The inverter outlet is in the upper bunk area and powers the TV.
I was disappointed to see that our inverter is a modified sine wave inverter and not a pure sine wave inverter. Everything I read says it's not safe to power laptops and cell phone chargers with a modified sine wave inverter. I guess I will have to switch it out but it will have to wait as I don't have the money to do that right now.
