Just like the Nightmare on Elm Street our electrical problem went on and on. But I think we have finally arrived at the Final Chapter. To make a long story short, it seems that the problem is with the 50A socket on the campground’s electric box. It wasn’t that the socket was broken, just worn. Ted, our intrepid campground host, is going to try to fix it tomorrow.
In the meantime we are running off of the 30A socket. Both the refrigerator and the water heater are happily running on electricity again.
