Make some calls as there are some dealers anxious to move Airstream, and especially 'old' Basecamp product. We picked our new 2007 up in Vegas for $12,900. It has the 20 inch wheels and the rest of the goodies. There are some minor upgrades on the 2008, but nothing drastic.
We are dealing with Airstream for some issues with the doors right now... they have been helpful, but unfortunately we live 1000's of miles from an Airstream dealer. This fall we are making a trip to the NW 'states, and will get some work done on it then. We have to drive on a lot of gravel to get out of where we live, and the rear doors let tons of dust in.
It is a nice unit though, tows easily behind our Tacoma... but I am going to see if a single arm WD hitch will fit on it anyway... it is a bit heavy on the tongue...
The beds are comfy for me, but if you are over 6 feet it will be tight.
I think the only servicing issues might be if you destroy it... all the 'little' parts are standard RV gear, but if you really damaged it they might not have some of the bigger pieces available.
Once we get a few little things sorted out, it will be perfect for us.
