Used trucks are dirt cheap right now in Collyfornia because of the new smog laws. Make sure anything you look at can be registered for 5 years or so. My FIL's 2004 Peterbilt with a 550 Cat can't be operated in Collyfornia (without $20K plus in modificatiions) after 2014 because of the smog tiers. Every trucker knows this and he can't sell his truck.
