re-read what? Do you not know what a pickup bed is? Why do you need a luggage rack when you have a pickup bed? Nobody is going to mount a luggage rack on a bed cover, because then its in the elements. If your bed is that full, and you still have luggage to add too, then you're going to remove the cover and use a tarp to cover it, or you get a cap. For you to be able to mount a luggage rack to a cover, it would have to be a hard cover. Hard covers are securable. What do you just have enough room for in the bed that you want to secure, that you would take with you and your luggage, yet don't want to secure your luggage? You also shouldn't need your luggage while driving, so when you are done you can secure it in the cab or take it with you. I promise, its not a practical idea.
