Ok, I see the thread on the SMOG inspections for California, but I didn't want to sort thru multiple pages of posts. I currently live here in Texas but I will be moving to California in probably a year or so to attend Seminary out there. I am currently trying to sell my 3rd gen truck right now and trying to use the equity I have in it to go towards a really good used 2nd gen Cummins to replace my 3rd gen when it sells. How can I know that the 2nd gen truck I buy will meet the California requirements when I end up moving out there, and what parts or service would need to be performed to the 2nd gen truck in order to get the truck up to spec when I move out there? Most of the 2nd gen trucks i've been looking at (there are some nice ones in the TDR classifieds... LOL) have mods on them, so what procedures would I have to take in order to get a modded truck to pass? If somebody could educate me on this i'd really appreciate it. Thanks very much!
