I'm looking to buy a seven or 8 seater to sleep and camp with, I was originally thinking of removing the middle row and sleeping on the floor but seems a faf to remove and put back in. I have seen the 8 seater seats laid flat as a continuous bed(albeit lumpy) to then put a mattress on. I like your sheet separator idea with extraction for using the rear as a change room/toilet with extractor. Would love a picture please, I'll be taking a portable toilet also and keeping the third row up on the sides until it's bed time as mentioned above, hopefully finding place for all the stuff under and behind the seats. Attached a pic from another post of the bed layout.
