parts for 1974 20' Argosy motorhome

[birdsurfs]

Just got into a 20' Argosy that runs very well but with the exception of the bathroom has been gutted. This is a rear bedroom model with the bathroom place directly behind the drivers seat. The entry door is right behind the passengers seat. PO saved most all of what he took out plus he had collected a wide variety of misc. parts from some non road worthy 20'ers. What is missing is the drivers side far rear lower panel that includes the side driving light. Hoping to buy or trade parts for this piece. Would love any tips on where to see pictures or diagrams of this particular floor plan. This is my first Argosy so all friendly help and advice will be appreciated. I'm in San Diego.
Thanks,
bIRD

Welcome to the Airstream world, and more specifically the Argosy motorhome world. You've got one of the more rare motorhomes ever produced by Airstream. I search for a 20' for some time before my 24' came on the market at an excellent price. As for floor plans, you can see the original Airstream documents here: Airstream, Inc :: Specifications

There's also some serial number info here: Airstream, Inc :: Serial Numbers

It seems like you have a mystery on your hands, though, or else something super-rare. According to what's on Airstream's site (which may not be entirely complete) it looks like the only motorhome made as a 1974 model was a 24'. Also, I've never seen / heard of a 20' model that had a rear bedroom / front bath. If this is factory, then it's truly rare!

As for getting the panel you need, there's a couple of good sources: The Airstream factory and Inland RV. Keep your eyes on eBay for a service manual, that will be very helpful, too!

Here is a link to my Argosy 20' page. I have pictures of several front bath models including your 1974.

I also have some floor plans for your 1974 Argosy 20 at the bottom of the page.

Well, today is one of those days where I will go to bed happy. I learned something new and best of all, it was about Airstreams. I had no idea of the 1974 20' Argosy moho and what seems to be a layout unique to 1974? I've looked at Fred's archives before, but never paid a lot of attention to the 74's. That is a truly neat layout, although I'm not sure I could have someone "going potty" right behind me in the driver's seat as we roll down the road.

Enjoy your new Argosy. And never hesitate to ask on the forums. Someone, someday will have an answer for you.
