Seems to me that the furnaces in rv's are patheticly inefficient. There are natural gas house furnaces that are so good that the exhausts are plastic!

You have to realize, it's an RV, not a stick and brick house. Owning and operating an RV isn't exactly the most efficient use of money either, but it sure is enjoyable.
