If you want to camp around the Albuquerque area, Enchanted Trails Campground is where they hold the Vintage Trailer Academy. It's on old US 66 west of town a few miles. It's a great place to camp, and fairly close to Old Town.
Did your dealer give you any information on the WBCCI? If yes, contact your local unit and see if you can join them for a rally or two. That way you can see if it's your cup of tea before making a membership commitment. There's also the TAC (The Airstream Club). It's free to join, and they have TAC rallies a few times a year too.
