What's the Toyota Tundra tailgate weight capacity?

The tailgate weight capacity of the Toyota Tundra is about 500 pounds. There is no official rating from Toyota on how much the tailgate can hold and it is more just about what feels safe. If You happen to notice Your tailgate bending downwards then You will want to remove the weight from it. Your tailgate is just made out of aluminum and held in place with two cables that can be damaged if there is too much weight on it. If You need to haul things with Your tailgate down always be sure to put a red flag on it so that people behind You know that You have something hanging out of the back of the bed.
