We stumbled on this little gem during a freezing combined CMCA chapter weekend up at Kenilworth in Queensland. The Bribie motorhomers are a "bit different"! For instance they all have these dandy little solar lights out the front of their motorhomes! They don't want to get lost at night perhaps? OK, so to warm up the van in winter they simply heat up a ceramic flower pot. How legal this is we don't know so you try it at your own risk!
