Used GMC Cars for Sale near Quebec

This is my own truck, I still am in the process on repairing the truck, but I drive it daily. Im going to be taking the cap off as its not that good to see out of. Im also putting on a back rack to mount the antennas and the lights. Also going to put a soft tonneau cover to keep things out of the weather. (whole purpose of the cap was to keep things out of the weather, lol) But cant see out the back window. This truck is an ex work truck. It came with the plow when I got it.
