The forward base is a good idea, but I would extend that by saying drive a minivan or truck with a camper shell. Put a mattress in back and a portable heater--you can use electric or get a propane one for camping. If you get stuck somewhere or get tired waiting to be called, you can crash in back. I live in a very expensive urban area, and a lot of people who can't afford to live here commute in at 4am to beat the traffic then sleep in their trucks till 6 or so.
