i made one tonight at my grandpa's shop (he's an awesome woodworker). it's 48" wide and 30" deep and i think 6" tall. it sits on the floor in the back behind the rear seat and has 2 drawers in it, 1 for tools and 1 for junk. it's not done yet but when i finish it i'll get pics up. it would have been 53" wide, the full inside width, but i left room on the right side for my hi-lift jack. it's nice i can have junk in the back and still get to my tools and stuff now!
