We were on our "maiden voyage" with our new RV and were confounded that some of the outlets etc. were not working. I was pleasantly surprised when the service man came out to look at it immediately. He found the 'GFI reset" switch and pushed the button to reset. The other surprise was that they charged over $50.00 to "push a button>" I understand that you pay for expertise, but I just thought it was a bit much.
