I'd like one but I often carry my dogs in the back so I haven't bothered
It would be cool to make one that would simply swing down behind the back seat when you need the space for a dog.
It would have to be a little smaller in width and length so that it just cleared the floor as well as the humps of the cabin sides when folded down , but it sure looks like with some simple hardware, like a couple metal pipe straps and two 1/2” gate latch style slide boltsit wouldn’t be that hard to do using the metal seat brackets for the swing point and the plastic grooves that keep the oem vanity cover from retracting, to hold it securely in the up position.
The hardest part might be keeping it from rattling too much but I’m a big fan of silicone tubing and silicone tape.
Of course you couldn’t keep anything on it when it was on the down position but otherwise would be a useful shelf with the obvious added benefit of hiding what’s underneath it when in the up position.
