Item 1: Before purchasing either, try sitting down on the potty and shut the door. If you are an average guy, you'll have your answer pretty fast for both of these models.
Item 2: Also, pull the slides in on both of these models and see if you can still function inside the camper with slides in. You'll be convinced then about item 1.
Edit:
If you want a real test of the functionality of either of these campers, step inside either bathroom, shut the door, then have the salesman retract the side. See what happens. Now imagine yourself traveling with your family and everyone REALLY needs to "go." What happens then?
