Thanks again, beths11. On the first photo which shows that lower niche storage area at the rear, there seems to be about a 1 inch deep indentation on both sides so that if you had a floor panel to put over that lower storage area that was the same width as the rest of the lower floor, you would end up with a surface that was level with the rest of the lower floor. I don't know if I'm explaining myself well enough. Does it look like that might be the case? I don't think I would ever need that upper, longer level with the seats folded down, so I plan to keep that floor panel at home and always have that lower floor exposed. I would like to be able to have one continuous flat floor area there. If there is an accommodation over that niche storage to receive a panel, even if Tesla didn't provide it, I would be able to make one myself.
