I bought this Roll-X tonneau cover for my 2013 super crew short bed FX4 last July, it's in excellent condition. Paid $800, will sell for $550. All parts and mounting hardware included.
Works and fits beautifully and allows you to lock the tailgate and provide some security for equipment inside the bed. When rolled up it doesn't block the rear window like the Bak Flip style. I also like that you can set things on top of it when it's closed unlike a cloth tonneau cover.
I'm located in Fort Myers, FL and would prefer local pick up due to the cost and PITA of shipping such a large item but if you're willing to pay for shipping I can probably package it up and get UPS to pick it up.
You can learn more about it by going to the Roll-X website.
