Mike, there is a service available here for free. If you go to the "portal" page, on the right hand side you will see a box listing "Airstream Inspectors". You put in the area and type of trailer you are interested in and a list of experienced members that do inspections for free will pop up. I can personaly recommend it as it is how I found a member to inspect my trailer for me prior to making the long drive over to see it myself. Good Luck with your quest.
