I had similar experience early on. Backed into site and set up, too far back, cord wouldn't reach. Hooked back up to move forward a few feet, Cord reached fine. Got all set up and no power. Got hooked back up and went to office to get a new site. Office said did you click the breaker on the pole to the on position !!! Duh !!!
On a 95 degree day with sweat dripping down my face it wasn't too funny, but now I chalk it up to experience and let the wife hook up the electric check the breaker before I ever unhook. Boy, camping can be a lot of work !!!
