Our unit had 1979 off white wooden slats sort of woven into off-white & brown tweed macrame (sp?) thing. They rolled up or down (kind of like a bamboo shade) and somewhat matched the fabric on the couch, chair and end caps of the overhead storage. The valance and drapes are a contrasting Velux (like velour) brown simliar to that on the back of the driver & passenger chairs, the rear bed mattress coverings, and swivel chair.
We have re-upolstered all the above and installed mini-blinds. We replaced the swivel chair behind the co-pilot chair with a custom built (by us) bench style seat w/ storage beneath. Will it ever end...?
