Bryan Appleby gave some great tips in that article. I have been very impressed with his rig since I read an article about its development.
I really liked the technique that TiogaGeorge developed of having day camps and night camps. He would spend the day in public places like city parks or shopping areas and then would arrive at his night camp when time to sleep.
By using the day camp and night camp model you don't attract attention by being in one spot 24 hours a day. Also in the night camp location you don't attract attention by being outside moving around.
