Richie, Most likely your unit would orig. have had mini blind with fake curtain side panels on the rear windows (Bed,table,sofa), blind with valance only in the galley area, and a full curtain on the front bed bike door. You could contact FR directly to try to match them, but I think for fabric items it would be a long shot that they would have them available. They most likely would be able to sell you replacments in whatever is currently available (the currnet king rear slide has almost the same windo layout).
You might have better luck just having a local shop make you what you want/need.
I am close to being fed up with the mini blinds and am thinking about relacing them with full heavy curtains (which my wife can make), or roll up shades.
FYI, Most of the time, I keep a section of Reflectix insulation ( 2 layer silver foil with bubble insulation between the layers) in the rear bed window and in the front bed bike door window. I just cut it to fit and put it behind the blind or curtain. I also have sections of this cut to fit the roof vents for when we want to block the light/heat/cold.
The front bunk mattresses did not come with matching covers (at least mine did not). They are just plain. We keep a sheet on them, and the kids use sleeping bags.
The rear bed should have a matching quilted type bed spread. We added an extra layer of foam over our mattress for better comfort, along with a heated mattress pad (had to add an outlet for easy plug in).
We also replaced the foam in the seat/bench cushions at the table. We used a much more dense foam for better comfort. Just ordered it on-line, cut to fit the sizes I specified.
