RV Repair: Jayco Pop-up, amp breaker, tow vehicle

Question
Checked fuses, but Electricity is getting to the Trailer inside, has tow lights. Was plugged in lights, and air went down in middle of night.

Answer
Laurie,
      You said you are getting electricity inside the trailer.  Where are you getting electricity?  Depending on what year Jayco pop-up it is you should have 2 or 3 breakers.  If there are three one will be a 30 amp main breaker, a 20 amp breaker for the air conditioner and a 15 amp breaker for the converter and the receptacles.  It sounds like you have either tripped the main breaker in the camper or the breaker where ever you are plugged in at.  But if that was the case you wouldn't have any electricity.  The tow lights are getting power from the tow vehicle, where else are you getting power and is there a battery on this pop-up?  Please let me know and I will assist as I can.
