I am wondering if there is any heat in the water bay under my bus if I don't have the Webasto on? It has been freezing every night for the last couple weeks, and I have been assuming that I had a small electric heater in the water bay such as in my last Marathon, but after reading the manual today, I don't see that this is true.
I suppose I have been fortunate so far that I haven't had a pipe to freeze. If I have to run the Webasto every night to keep the bay warm, I won't have any diesel left by the time I start to leave.
