AirSpleen

Hello
I am a Spanish,and looking forward to buy a 25´ AIRSTREAM from the 60-70´s, My idea is go to USA to buy one ( as soon as I finish with the legal matters),The legal matters in Spain are terrible with vehicules from USA (also with caravans), due different legislation.
To know if I can put Spanish plates, the register office ask me for documents from the AIRSTREAM
After a long conversation, they accepted if I can give them a copy of the documets (title I think) of the same or simmilar AIRSTREAM caravan that I want to buy.(serial number, measures,wheigths.....)
For this reason I am asking help:
I dont need the serial number, only the amount of numbers and simbols that the serial numbers has.
I need the rest of the information of the title.
Will be very nice from you If you can email me a copy of a title of the type of AIRSTREAM what I am looking for. (25´from the 70´s).
I have nobody to ask.Please help me.
Luis
