Carpeted platform in place of sliding tray

Hey just removed my sliding tray from the back of my 5th Gen. I'd like to have just a flat surface in place of it but anyone that knows can tell you it ain't flat. Probably a sheet of 3/4 ply with supports and carpet carefully measured would work. I'm not concerned about leveling with the seats folded, I don't intend to sleep back there. Any vids (I searched youtube) you guys know of to assist? Also is it okay to post FB Marketplace ads here? My tray is for sale.

 

Interested, where are you located?

There are a few platform ideas in this thread, including some that just level the cargo area with the folded seat backs. Some are simple, and some are pretty fancy.
