When an Airstream trailer has been parked for several years, many things can happen that you should address, before you invest a lot of money into repairs.
The first major thing to do is to make sure the trailer is water proofed. Check the window, access door and entrance door gaskets, and especially the sewer vent pipe cover gaskets that only last 2 to 3 years.
All of the appliances should be checked over and repaired if necessary.
The largest bummer is the axles. Any torsion axle that doesn't move for a long term but is carrying a load, will help the rubber rods within the tube to deteriorate. Plus, torsion axles only last about 25 years when used properly.
There is an article in this forums that will teach you how to check them out.
Make super sure that every LPG fitting is checked for a leak, however small.
