I had 2 10's behind the seat of my reg cab '05, but removed them because I needed the space and I liked pushing/leaning my seat as far back as it will go considering i'm 6'5. I would like to possibly build a box that would go behind the center jumpseat so I could still lean the seats back or something that would replace the jumpseat all together. I was wondering if any of you guys had any suggestions? Pictures would be great too if possible!
