How many of us are there? Owners of Dodge based RV's?

I just got my first RV ever. It is a 1976 Dodge Xplorer 260. I am totally ignorant about this and I am planning on living in it full time while in school here in San Diego. Hopefully I will be able to save enough for something I can take all over the country, if this one doesn't work out. It only has 27k original miles on it and has been maintained - the guy has the records. So anyway, I will be here for support from y'all hope it's ok.
