There is an ongoing fundraising effort for a proper restoration. The idea is to get the trailer back to original condition and roadworthy so the museum could use it as a traveling exhibit. The SNU has received verbal commitments for parts and some other progress. The next step is to find something like $100k for the restoration.
There were only about 4 or 5 of these gandy dancer bunkhouses built in the 60's. Even Airstream needed a bit of 'reminding' before they'd own up to them ;-)
