I just bought my first aistream. I am a newbie and I got my first airstream (a 1968
28' ambassador) just yesterday. Today I discovered an exterior plug just to the left of the door. Obviously it's a plug unit so I didn't want to start my question with "what is it?", but I was wondering why would a plug be needed on the exterior of the airstream? Since I will use my airstream as an extra room that will be situated near my main house, could I somehow hook up an exterior plug from the main house power, plug it into the exterior plug on the aristream and power my silver baby up through this?
