You have a 72" Aeroflat sleeper. They were never made as a 2 bed sleeper that I know of. You need either a 72" Aerodyne or an 84" Studio (or Diamond) sleeper to have a 2nd bed. The upper bed eliminates a lot of storage space. Look in some KW sleepers and you will quickly see what I am saying.
Yeah I'm gonna end up taking out the pass seat this weekend. I don't have passengers very often so I figured that would free up some space and I can put a fridge in there along with a couple other little things
