The power is plugged up correctly to the outlet, the breaker outside is on. The actual Camper's breaker's are ON, and they are getting power (we checked with a tool). No lights, Fans, nothing.
Your lights and fan are powered by the trailer's 12 volt battery. Make sure it's installed and not run down.
12 volt power is protected by automobile style fuses. The circuit breakers control the 120 volt power. Look for a fuse box / power center inside the trailer.
The 120 volt AC power runs your 120 volt outlets, 120 volt appliances like the microwave and the converter that produces 12 volts to keep the batteries charged when you're plugged into power.
On a pop up camper you may also have a problem with the jumper cord that goes to the roof if all of your dead lights and fans are there.
