Our rig is 3 hours away at the dealership right now, so I can't measure, but I don't think the extend-a-shower rod mechanism would be long enough to utilize with a 90 degree installation, and give you enough room.. Not sure....just saying.
I know we look at it as one of the best mods we made to the entire bathroom area, but I installed it the way it's shown in pictures.
