Hard folding truck bed cover - here's a link to a new one: https://bakindustries.com/bakflip-f1/2010/toyota/tundra This was bought in 2015. Still functional though has wear and tear. You get brand new rails with it (I bought a new one and kept my installed rails). This works with beds with cargo hold down systems installed (and without I would think). Instructions, and all hardware included.Fits 2007 - 2021 Double Cab Tundras with 6'7" beds. We can verify fit before purchase.
