seems like a cool base platform, what engine does it have? and is there a winch behind that fairlead? For bedding with full size vehicles i always like to use an air matress in the back, especially with pick ups they make air mattresses that are shaped to go around the wheel wells. With a kitchen it depends on how much cooking u plan on doing, for me a couple storage tubs a roll out table and a camp stove is enough, if u want to cook more some kind of slide out with everything in it seems to work the best. Im not sure what u mean by stuff so i dont know what to suggest. If u mean gear a drawer system is always nice, plus if u do a drawer system with like a platform on top for bedding then u can incorporate ur kitchen into it to pull out.
