Has anyone modelled, to spec, the cab of a thirdgen in any CAD program? Specifically the back seat and hatch area.

I'm toying around with the idea of removing my backseats and designing a glass box that extends from the back of the front seats to the gas tank hump.

 

i didn't remove my seats i just folded mine down, but i built one like this........

 

That is a great looking box!
I have never seen someone pre-carpet the side panels before installing. Good idea.
I usually router an 1/8" rabbit around the perimeter of the side pieces so I can tuck the edges of the carpet in it to hide any seams form the top or the sides.
What cu ft you running and what is going in it?
