I do have some experience with Dickson since I visited it a couple of times, and with door stoppers and other dorms.
I don't think Dickson is slanted on the slope, so the door most likely won't close shut, like the other dorms on North. The doors are basically stationary.
Make sure you're doorway is NOT sloped down meaning that the hallway outside and the floor inside is not on the same level. 'Cause that makes a doorstop useless. I had encountered that in my previous dorm.
Rubber stoppers work fine with carpeting.
