Retronaut has a neat pair of photos today of a proposed desert crossing vehicle. It was designed in the early 1930s to safely cross Central Asia. I wasn't able to find any additional information about the vehicle that wasn't in German. However, I was struck by how similar it was to the Khetanna, Jabba's sail barge in Return of the Jedi. Take a look for yourself.
and here's a model version that show's it from a more comparable angle.
