Not sure a brochure will be of much help. I recently purchased a used 1985 Keystone and a bag of paperwork came with it. The 1985 owners manual does not show bed sizes, only how to set up both the main and lower couch into sleeping positions. I also have the purchase order for the camper which is one sheet showing all available options and the prices written in of the ones chosen. Again no mention of standard or optional bed sizes. Finally there was a 1994 Color brochure and a Grandby fact sheet that indicated that all campers came standard with a queen size bed and that the couch makes into double. The fact sheet has a drawing showing that the bed area projects 32" from the front wall of the camper. Just to be a little more confusing I purchased a Grandby new from the factory in Denver in either 1984 or 85 and vaguely remember paying extra for a queen bed, but that was a long time ago and I won't swear to it.
