Rob, I have had three trucks with hard tonneau's on and I loved them. The security was excellent and we never had to worry about what was in back. The problem was if you had to haul something taller that the bed you had to remove the cover or leave it open. I can see that a roll up cover would solve that problem and still give you some security. I have seen the aluminum covers that can be removed in sections and those look great. Good luck with your choice.
