ok so priorities - hooked up the stereo so I can work with music on but noticed when putting it in there are 4 pairs of speaker wires behind the stereo in the front cabinet but only 3 speaker locations in the trailer, left and right up front and in the bottom of the overhead cabinet above the sink area. I presume one should be by the side goucho across from the kitchen but can't find any evidence. Was there a 2, 3 or 4 speaker option in 69? No sight of holes or patched areas. Removed outlets etc on that side to see if it was back in the wall but couldn't see. Any 69 owners out there that have the same layout and have a 4th speaker?
link to trailer with same layout as ours:
