Found this on the San Mateo, CA Craig's List as I searched for used Class Cs . . . Snow Cabin Telstar 27' I'm thinking that the wood burning stove might be an issue.
The stove doesn't bother me as much as the insulation. He basically added insulation to the inside of the wall and built another wall over it, as he points out on the cabover window. This creates multiple layers of moisture barriers that will effectively trap condensation between the layers and rot this thing from the inside out.
