i have a chevy/gmc crew cab tonneau cover for sale. i bought the truck a couple of weeks ago and it came with it . i wanted a tool box so it would be a good deal for anyone. it has barely been used. it is black hard plastic, very durable, lockable, has hydraulic shocks. it is rated so that you can actually stand on top of it if you need to. the guy paid over 700.00 for it new. i am asking 200.00. thanks. give me a call 850-376-3999 if you have any questions.
