Model years change over earlier than calendar years. It could be a 1970 model that was prodcued in late 1969. If you have the serial number from the plaque near the door, that can be decoded to clearly identify the model year.
For a 1970
Caravel the serial number should be in the format of:
Ohio: B 18 T 0 J NNN
California: B 18 T 0 S NNN
For a 1969 Caravel it should be:
Ohio: O D 18 9 J NNN
California: O D 18 9 S NNN
where NNN is the build sequence number, T=Twin beds, & D=Double bed.
