Have an aluminum roof rack that came off my old 2014 F150 6.5 box. Swapped trucks and now this is just sitting in the yard. Measurements approx: headache rack is approx 25inch high. Unit is 68 inch wide. 81.5 inch long and about 80 inches between the front posts to the back posts. I have a backflip cover that goes with it. No keys for the lock and the cables are a little mangled, but it keeps stuff dry. Take both for $300 obo.
