I agree with Hampstead 38 that the best book you can ever read is ,"these forums". From the 1st day I saw an Argosy I knew I had to have one. I found my way here and the rest is history. You can learn just about everything you want to know about Airstream and Arogsys here. If you still have questions just ask and you are pointed in the right direction. There's a wealth of information here.
Good luck with your search in finding your perfect Airstream. I started out looking for an Argosy motorhome but ended up deciding on a trailer after a lot of searching. Mine is perfect for us and we love it. Good luck in your journey and welcome to the forums!
