I want more dry storage for hunting/fishing/camping. Right now I have a tool box in the bed and will take out my kids' car seats to fold the rear seat up when I need some space for those trips but as they get older, they're going to start coming along and I'll lose the cab space. I was leaning towards a camper shell, but my wife is nixing that idea. Does anybody have one of those solid tri-fold ones that are made with aluminum or composite panels? I'm wanting something that gives some security so the vinyl ones are out, and a little more flexibility than the fiberglass ones offer. Anybody have opinions?
