Figure I'll post mine since I'm relatively new here (posting, at least)
My goals for this platform were to: create a flat sleeping area (since no 3rd row or sliding tray), leave as much headroom as possible both for camping and for bike storage inside the vehicle, have a little space underneath for minor tools like ratchet straps, tire iron, small wrench rollup, etc., incorporate a sliding table for picnics/camping, and not drill or cut any plastic because hopefully one day I'll upgrade to a bigger platform and it would be nice to be able to start from scratch (basically back to stock just in case certain trim pieces are needed)
My favorite part is the modular rail. If it's not being used, it's all totally flush and you can still easily slide gear, coolers, etc. in and out without hanging up on anything, and if you're sleeping back there, there is nothing poking at you. Hides flat under the floor mat. I have made a few tie down accessories and a bike mount for it that all work really well, and the T-nuts underneath the rail can move to wherever you feel like placing them.
The whole thing bolts up to the factory tie down points, and just relocates the D-rings to the top of the platform, so those are all still usable as well. It installs/uninstalls really easily, and looks factory.
