Expo Trailer must haves?

[Jonovision]

hey guys,
I'm thinking seriously about starting an expo trailer project build, and of course I have my list of wants:
-articulating hitch
-cooler/fridge slide out (2?)
-solar system, with pivoting mount
-inverter
-deep cycle battery
-fold down table/exterior storage cabinet with fold down door. room for food prep, stove, coffee maker etc.
-integrated 20lb propane tank/manifold capable of running multiple appliances
-capable of running 285/70/17 (matching spares with the truck)
-2 spare tire mounts
-pop up awning mount
-levelling jacks
-tubbed fenders
-side lift box lid/toneau supported on struts and utilizing heavy-duty latches
-capable of supporting roof top tent
-frame mounted rear recovery point (hitch receiver?)
-leaf springs/struts
-2x 2-NATO style jerry can holders
-area lighting
-10lb fire extinguisher mount

the catalyst for this is a utility trailer made from the frame and box of a Toyota NR-15 on the local buy and sell

being a Toyota guy, this is just too good to pass up, and if this thing is in even fair condition it could be a pretty rad base for an expo trailer build.

what else would you guys consider to be necessary equipment for a base camp trailer to be used for up to possibly 7 days?

nice options
thinking that truck would be a heavy trailer as opposed to a M416 per se
you could build one, not sure if you're familiar with http://tventuring.com/trailerforum/index.php
its an awesome forum for off road trailers, lots of ideas over there...

If I do end up getting this toyota box I'll likely only be using and heavily modifying the frame, and hopefully utilizing the tail gate as well

My very best advise? Keep the weight down, use as light as possible materials. A few years ago I stripped ours back down to the frame and used aluminum wherever I could, primarily the floor. 7075 1/8" sheet over wire mesh. Just that simple mod lost nearly 70 lbs of excess weight. I see some of these big heavy expo trailers weighing in at nearly a ton empty, load em up with gear, water, tents, etc etc and they tip the scales at 22 to 2300 lbs and more. Thats a lot weight. Ours tips the scales at right around 800 lbs fully loaded.
