I keep coming back to a bed cover as well, especially Diamondback or Highway Products due to how they operate and how easy they come out.I’ve racked my brain about this quite a bit. On one hand, the very large dry and secure storage of a shell would be great. But there are always those instances where I need an open bed to move large cargo.
Option 1 was to look at an aluminum shell. Much lighter than fiberglass. But still a pain to take off and store.
Option 2 was Softopper. Offers the large dry storage but no security. And looked kind of cheesy.
Option 3 was a tonneau. Not as much storage but not bad. Secure as well. And very easily removable and stores in the corner of the garage. I ultimately settled on a tri-fold model. Wish there were a go go gadget shell. For now, a tonneau cover works.
