The Tin Wheeler came with plain white curtains that were somewhat worn. They were yellowing and had rust spots on them. They had no ties to hold them open so that all the windows were partially obscured at all times.
Some of the newer Airstreams have aluminum blinds that we felt looked much better. Sarah found a shop in Stoughton, MA, Blinds to Go (http://www.blindstogo.com/) that would custom make blinds with an amazing turn around time of just 48 hours. She ordered them on Monday and picked them up yesterday (just 3 days later).
We installed them this morning. We are very pleased with the results. They are very sturdy and seem well constructed. They give a much more modern look and are in keeping with the Airstream aluminum theme. Here are a couple picture of the newly installed blinds:
