I am considering buying a stand alone generator for use when dry camping. I think I would like to have a propane operated unit but the lack of that type on the market makes me think there are some unknown reasons for their scarcity. I think that being able to connect to my coach propane tank, the lack of smell and not having to carry around a gasoline can would all be good reasons to go with propane. Can someone out there give me some pros and cons of using propane?
