I made a cargo deck that converts into a camp table. Mine doesn't sit as high off the floor of the Jeep but it also slips into the front factory seat brackets and interfaces with some additional custom brackets that mount to the rear insta-trunk threaded holes in the back. Whole thing can be install or removed in about 60 seconds without any tools. And there is a matrix of threaded inserts all over the cargo deck so it's easy to screw in an eye bolt wherever you need an anchor point.

threaded inserts. They are t-nuts that have
been glued in place with Gorilla Glue to make
sure they don't pop out.

"hinge" so the deck and be pivoted

At the campsite the cargo deck converts into a camp table
by folding down the legs.
We just finished making another version of this for a friend of mine. His is much more built-in and has a semi-permanently mounted bulkhead that houses a subwoofer and two amps for his stereo. The bulkhead is integrated with two sidewalls that extend to the tailgate and "wings" that cover the wheel wells. The cargo deck / table portion sits on top of the bulkhead and flushes out with the top of the wings. Recessed into the top of the deck are some aircraft-type logistic track for cargo anchors. The deck can be removed and legs screwed into the bottom of it for a camp table. His is tall enough that he has a lot more storage under it than me, but it makes his rear area unable to mount a back seat, which isn't a concern to him.
