Can anyone tell me how to assemble the bed in the main cabin on a 1985 H23. It appears that the floor boards come up and are placed vertical. My floor boards stick up aprox 1" above flush with the seat berths, these could be trimmed or notched to reduce these to flush ? Are the seat back cushions used on top of these once place verical or is there another piece of wood that I am missing which would lay on top of the floor boards/slats once place vertical ?..if this were true then the hooks on the back of the cushions would be in the way ? Can anyone provide help, a diagram or a prefered modification to make this bed functional. Thanks for any assistance you can provide. AJ
