This is the start to my first project on my new 4Runner, just the idea of what will eventually be a final project... Just a quick model I made with scrap wood I found around the house

Base of the project


My subwoofer fits right underneath, covered by the first top platform


The Second platform slides out to make a bed platform


To secure the two platforms together this is what I did


A hole on the bottom of the second platform


Then the screw sits in the hole and locks the two pieces together


The second platform sits right on the folded up seats


Then I added sides and a bottom to the structure to make it a toolbox


Next I will add a door (or drawers) to the toolbox
I will also be adding a couple more features and compartments in the near future, I will post when completed... Just wanted to know what you guys think of it so far!
