I read an article yesterday from Mother Earth News about converting the VW bus to propane. Since then I have talked to Dan and he says that this is old news. I knew about conversions to propane since the first oil panic in the 70s, but I never read an article that made it sound so easy. I like that the article says that you can switch back and forth to gas or propane. If I did it, I would put the tank inside under the "bed". I have been told that you have to mount it outside. If that is a fact, then I wouldn't do it, Ugly. I was told way back in the 70s that gasoline is necessary for lubrication. True False? Since I am sure that many of you out there know all the pros and cons, I would appreciate filling me in. Propane conversion, good? Bad?
