Bobby Mackey's / Thomas House Weekend

Looking for a retractable tonneau cover for my F-150 that offers good security and weather protection. I use my truck for work, so I need something lockable and durable. I also want a cover that’s easy to open and close since I’m constantly loading and unloading tools. Some covers tend to get stuck or become hard to slide over time—any recommendations for a cover that stays smooth even after years of use? Also, is it worth getting an aluminum one over polycarbonate, or is there not much of a difference in daily use?
