Damon: According to the information on that post Airstream stopped using O for Overlander in 1968
. Our AS is a 1970 so even if there were some over run of serial #'s it seems like 2 years would be a very long over run. Besides it looks exactly like the zero's in the rest of the s/n not an O.
Bambi: The 6th digit being a J recognizes that it was made at the Jackson Center, Ohio facitlity so yes it was made in Ohio.
Still puzzling since the first digit is supposed to be an I,E, or L . Ours is a Land Yacht Safari so the 0 is not explained in the "normal" serial # configurations. This is very curious. I have tried to attach a photo of the S/N tag. Tom
