We have recently joined the Caravan Club. I have found the newsletter and magazines really helpful in choosing a caravan.
Dont own one yet, the thought of towing gives me the heebie jeebies. But I know the CC run a course on towing which will ge helpful. DH & I will both do it, I have a mental image of towing the caravan around France during the summer holidays and having a great time in a floaty hippy kinda way. 
I grew up with caravanners and we had a fantastic time, although I am not sure that I will allow my children quite the same freedom that I and cousins had.
