My wife and I also just bought an Airsream. We bought from RV Legends in Waterbury, CT, great people to deal with! We are on the west coast in FL for the Winter returning to Milford, CT in May.
We are deciding what avenue to take also with joining WBCCI. I have been in touch with the Suncoast unit here on the west coast of FL.
There is a rally in Feb. in Sarasota at the fairgrounds. We are going with our AS for the weekend. This will give us a chance to see first hand what the WBCCI is all about, I think it will be a good time. Google it and you may find this would be a good thing for you to do also. If you want to contact me send me a PM.
