I am really debating one as well I want something secure that can't be easily broken into but I also want fully usability of my bed. It seems like the only option is a soft roll up cover, is there an option I'm missing?
I love my Agricover Lomax hard tri fold. Bakflip and Gator have always leaked like crazy for me, but the Lomax seals very well. After twenty minutes of heavy downpour through the Georgia mountains yesterday there was no water in the bed. I personally think it looks cleaner too. Install was quick and easy, and removal of the cover takes seconds.
