I'm 5' 8" and I have a 2011 GMC which is one of the last trucks built with a low height compared to Ford, Ram, and the current GM trucks. It's not practical to even try to reach over the bed in my current truck. I've just always climbed in from the back to get things. I have a new Ram 1500 ordered with Rambox. I know it will be impossible to reach over but I'll have all my gear in the Ramboxes so that will be an advantage over reaching things in my cross mount toolbox. For anything in the bed, I'll access through the back as usual. Any time you trade for something different, there is a trade off in some area.
