Other than sitting flush with the rails it sounds like you’re describing the Diamondback covers. It’s what I have and couldn’t be happier, check them out.So taking everything in consideration what would y'all say is the best hard top flip for someone that wants one that is very water tight, able to keep water tight with having the cover down and then closing tailgate, flush with bed rails, heavy duty enough to stand on, able to flip open the third panel to gain access to entire bed, and easy to remove if needed.
