Wow ...she's a beaut!!! Here's a suggestion where maybe financial needs can be met AND you can keep your gorgeous gal.
Contact the film office in Chicago: "http://www.ci.chi.il.us/FilmOffice/". Chicago gets a lot of 'location' movie work. Contact the "Oprah" show as well "http://www.oprah.com". Trade show folks, etc. Put your Airstream up for RENT. Ask for a deposit (usually around $500 to a film company) and somewhere between $200-400 a day rent. It's been some time since I worked in 'the biz' but these rates are probably not too far off. The film office should be able to give you more current rates.
HINT: European companies LOVE Airstreams, old Americana, anything funky with a 'high cool' factor.
Many times a company will need a groovin' trailer for a 'show trailer'. It will appear in the movie, music video (GREAT place to rent, quick money, lots of fun and great folks), or on a commercial.
The other option is that many company's need trailers for their stars but some movies and budgets are too small. They cannot afford the 30 foot RV for an up and coming actor.
I worked on Brooks & Dunns video "You're Gonna Miss Me When I'm Gone" ...the person in charge couldn't find a suitable RV for 'the boys' during the day while we shot. So I hit the classifieds. Found an AWESOME couple in Houston, Texas with an RV for sale (we shot in Del Rio at the old "Alamo" John Wayne set).
I explained what was up. They rented their rig for about $300 a day, the company paid for some of their expenses, they stayed with the RV and drove it for the video and got $1 a minute to rent their cell phone (before everyone had cell phones). After the shoot they decided to keep the RV and do this sort of "full time" or as much as demand would call for.
Just check around. Call photographers who do catalog shoots. Shiny things are always in demand. Believe me if you hit the right vein up thataway you could rent your Airstream all the time and make a nice side income. You are very blessed to be in one of the biggest areas for film making. Keep us posted and best of luck! If you need any help with this stuff please email me:

p.s. 4 features are slated to begin filming in Chicago very soon. Make the pitch :-)
