Newbie looking for input and clarity

Hey Ya'll,

I am brand new here.

I have been considering buying an airstream for quite some time. I think they look awesome!

I found an Overlander Land Yacht International which I am thinking about purchasing and restoring.

It looks like it is fairly original, and it needs some TLC and work.

I found a tag on the front of the trailer.

The serial number is:
127TI-J2954

The owner believes it is a 1973, but he is not sure himself.

I have a couple of questions to start...

How do I find out the floorplan, and how it was originally optioned?

How do I go about finding out what it is worth?

Thanks in advance,

Elon
