Over the cab storage

Best way? Not sure what you're asking. We just load stuff up there, don't generally have a problem with stuff falling out. It's easier to put stuff either in boxes or some type of container. I keep my camera bags up there as well as my tool box. I have to put the inflatable kayaks up there because they won't fit in the outside storage areas. Ever since they stopped putting windows in the front, it's not as much fun to ride up there.
