I was wondering the same thing.Has it been confirmed that all of these settings can be used at highway speeds? I believe they use half shafts like the X. With the X, the half shaft angle becomes too great at the higher settings and the higher settings can only be used at low speeds. Even the normal setting in the X causes intense wear on the half shafts.
Great catch of an R1T in the wild! While the gaps do seem to be less than what we'd like to see, I agree with Skyote and Babbuino that the final product will likely be neat and tight. What surprised me here are the shiny surfaces on the tops of the bed rails and the top of the tailgate. I guess I'm conditioned to like the rubberized texture we normally see on our trucks. Gauging by the reflection off of the top of the tailgate, it looks a little deformed. It appears there are detents, possibly above attachment points to the tailgate(?). I'm not sure I don't like it more than the rubberized texture I'm used to seeing but fear it will get scuffed up easily. Also, I can't recall if I've bitched about anything today, and it's almost midnight, so there you go.
