So with these doors, when you back up to a loading ramp the door must swing into the trailer then you need to reach in somehow and pull it back out again? I think I will stick with the sliding door also. The one on my corn pro works very nicely. There is a very good feeling when the animal finally goes through the door and you can slide it shut from the outside. And the single full swing also works well unloading at the sale barn opening it safely from one side, "out of the action" as noted above.
