Jim,
The
12V receptacle (cigarette lighter) is a handy option. I have actually added a few to our MH in more convenient locations. You can get appliances that run off of
12V. My favorite is our crock pot. I can start a meal in the morning when we leave and let it cook all day while we travel. When we arrive at a camp park the food is cooked and ready to serve. Of course in our motor home we have the benefit of smelling the cooking during the day but you can always slip back during rest stops.
We will meet you in Madison at the art fair just let us know when you are coming in. By the way yhere is no such thing as an "econo box" Airstream as you will soon find out.
