I was thinking about getting one of these tailgate bags, but then I remembered I had a motorcycle tank bag that uses heavy magnets to mount to the tank. I sold the bike a few years ago so I stuck the bag onto the tailgate and it works great and is solid. If I was going to spend more money on additional storage, I would look into a really big tank bag with magnets....
