Here is my drawer set up, though not as pretty as some still very functional and lightweight. I found these drawers on the Expo forum for 100 bucks.
Originaly these were a triple stack, I cut one off and was going to cut the other off and make a level platform but I did a test fit with the fridge and really didn't like how high up it sat. I also had plans to build a wood platform over these drawers but I am trying to cut down on weight and since I will be using a roof top tent there is no need for a sleeping platform. I also like to use duffle bags to store stuff rather then hard containers because they are much more compact.
I built a simple slide out for the fridge using a slide lock and ball bearing slides bolted right to the bed. I do plan to change to a real fridge slide but for now this slide works ok and didn't cost me anything because I had the parts on hand. The straps to hold the fridge tight are boat transom straps 4' long, I will be adding one to the back to even the tension.
one drawer holds my pulpal, max axe, winch control, larger tools, gloves and small shovel. It is actually easy to pull out considering the weight.
another drawer has misc. straps and ropes, small spares like u joints and hoses. Also contains bug netting and stakes for the awning.
the top drawer is my kitchen, I like it being seperate from all the other stuff. I don't keep any food in this drawer, only the kitchen stuf like my stove, fuel, cookset, sink, etc.
I use a pelican case to hold food that I dont put in the fridge, plenty of space for a weeks worth of food for 2 people and the pelican case keeps the dust out.
