I have owned my truck for five years now, and I have always had issues with storing stuff behind my bench seat. It always slides down and comes out underneath my feet and seat. Yesterday I decided to make some storage bins out of some old/used 1" pine lumber I had laying around. I built them so they attach to the threaded sheet metal behind the seat using 12/24 bolts from the hardware store. It would have been better to use 1/2 plywood to gain greater storage volume, but the nominal 1" lumber I used has exact dimensions of 3/4", so it was not that bad. I framed the bins to lay flat against the back of the cab to support them and gain the greatest volume within the bins. Lastly I sprayed them with cheap black spray paint to seal them. Tell me what you guys think. These are nothing fancy, just practical and basically free for me to make.
