Best place to buy a Vehicle for the Pan Americas Road Trip! HELP PLEASE!!

Hi Everyone.
Partner and I are arriving into Los Angeles in November this year 2012 - in search of purchasing a suitable vehicle/camper/4WD
We are doing the San Francisco - Brazil Pan Americas road trip.
We are happy to venture out of CA to buy the vehicle.
Any info on what states are cheaper, where is best to look and buy, any good ideas on where to look etc would be GREATLY appreciated.
