Awesome, do you have a build thread going yet? I'd be interested to see how it comes together.
So far as the table idea goes it sounds interesting. I'm not sure I'm getting the whole picture though; would you have the tire mounted off the rear like a Jeep or under the chassis like I'm running? Either way, certainly anything is possible with some creative engineering - my biggest concern in design would be the weight of the tire/tabletop and the leverage being imparted on the mount.
I'm thinking it can swing out from either, off the side like a step side pickup, or off the rear like on my Isuzu Rodeo if I was to build one across the back of a trailer. The tilt system shouldn't add that much weight to the swing out carrier.
My trailer box will have two spares on it mounted on the sides forward of the fenders. The one on the right side goes in front of the entry door on that side so it will swing out for entry into the box. That's the one I was going to make tilt flat for a table.
My kitchen box will attach to the right side fender like you did yours.
I did a write up on the frame build over on Pirate about 2 years ago.
I made it with an IFS adjustable torsion bar suspension with remote steering and then got off on another project and put it on hold.
It has a lot of promise and will definitely be different because I can steer it around trees and rocks from the Trucks Drivers Seat by remote control.
Rather than Hijack your Thread I'll PM you some pictures.
There's a lot of stuff in that build.
I'll start a build here and bring everyone up to speed on the frame when I get back on it.
