What is “the original 1968 layout”? Is there anything special about it?
"Retro" is an adjective describing something that is coming from (or imitative of) a style or design from the past. Based on the cue given by the video title, we can assume "1968 layout" to mean the original layout (or arrangement) of the Airstream when it came out in 1968. Thus, we can understand the speaker as highlighting the fact that the redesigned Airstream actually has a new layout that is quite similar to the original. Ex: The set of the movie almost has the same layout as the original movie. Ex: The 1960s and 2000s layout of this house are quite similar.
