Welcome to the forum!
This is the best place to learn all things Airstream! Grab a cup of coffee look at all the pictures and read the posts... you'll be here about 2 years if you read it all....
What length of Airstream are you interested in? If you already have a tow vehicle and have done some camping you are nearly ready to go... just find a trailer! Any questions, just ask!
Awhile back there was a nice thread on what to consider when buying an airstream. I will post the link below, it might give you ideas.
We have a 1963
and love the sweet little thing. My hubby spent about 8 - 10 months restoring it, and now we are enjoying it as often as we can!
