I annoyed Duke's Parking and Transportation Services Office with calls and emails for months, but they refused to respond to my inquiries, so I--pressed for time--approached Duke's office of Public Affairs.
Apparently, vandwellers have been banned. Here's the new rule:
4.17.5 Overnight or extended parking of campers, vans, buses, etc., utilized as living and sleeping quarters within campus boundaries, is not permitted unless approved by Parking and Transportation Services.
While I acknowledge that Duke is a big, sprawling billion-dollar corporate bureaucracy, and they have to cover their asses, I still think the rule is stupid. I could name a hundred reasons why, but I've already done so, so there's no need to beat a dead horse.
Their reason? From one Duke spokesman: "As a private institution, Duke can determine the permitted and appropriate use of its facilities. Living in the parking lot is not permitted for reasons of safety, security, health and liability."
