Does anyone have one of these on a truck with the hard tri-fold bed cover? I'm curious if it can be flipped around while it's in the bed to allow full use of the bed. I occasionally hate to load wooden crates that are just under 6 ft in length. In my 2018 2500 with the soft cover I could load them and close the cover and tailgate to keep the rain off of them. If the extender can be flipped so that it is against the inside of the tailgate I would still be able to do that. But, it doesn't show that in any of the images online. Can anyone verify that it can be set up this way when needed? Thanks!
