Hmm, At the Curtis Wright museum in Hammondsport NY they have one or two of his homemade travel trailers, but I don't remember any of them being aluminum. But they were so cool! lots of neat stuff inside.I just did a search for the museum and came up empty handed except that Barnes and Noble sells a book on it.I don't know if the museum has a web page, but you should be able to get a phone number for them. Hammondsport is in the Finger Lakes region.
