Greetings Randy Cole: We have a 69 Globetrotter that certainly isn't anything like a 59 model year one. As Bubba L says, Airstream was mixing things up with their short trailers back in the late fifties and the fact they had two factories building trailers somewhat differently. Bubba L knows old Airstreams well.
The 59 Globe Trotter had a front "water closet" just inside the entry door. I saw one at the vintage rally I attended last summer. Our 69 Globetrotter had a rear corner wet bath that was also very small.
Many of us vintage trailer "renovators" change things around to make the trailer more functional and more comfortable. Other "restorers" refresh their trailers to be new just like they left the factory.
So here is a link from Airstream.com document archives showing the sales literature and floor layout for the 59 Globe Trotter 18'.
And here is a link to the 50 Pacer 18' showing the floor layout differences.
You mentioned 59 Globe Trotter and likely you have verified by serial number and title that is in fact what you own. You gotta post a couple of photos of your trailer when you feel like it. Here are a couple of photos of our 69 Globetrotter 21'.
Vintage Airstreams are a lot of fun.
