This could only have come out of the the Seventies. The colour is that odd pea green that was popular for kitchen appliances, carpet and apparently motor homes. And the name? Swinger! Is that a name or invitation? It looks like this might have been a Dodge but Google showed only a newer style Dodge Swinger RV. It certainly looks to be Dodge powered somehow. You may not want to Google Swinger RV from a work computer of course as there are some interesting results. There does appear to be a modern Swinger model sold by the odd make name of Georgie Boy.

Howdy,, I am in central Texas and found one like this but , the harvest gold period color trim. What would they be worth – if running / or what price if not ? Any guess and engine is ? , transmission ?
Thanks
I don’t think they are worth a ton. This one was offered for free on a local classified site.
