I was looking into a small, easy to set up trailer a few years back and found these: http://www.chaletrv.com/

Apparently they increased their product line, but if you look for the pop up trailers (hard sided, tipi style). What I like about them, is that they are insulated (may or may not be important) and you can have enough room in them to live. Then in 30 seconds you can move if necessary.
