I bought a new Gen 2 in Texas at the end of 2017 and brought it back to CA. The process is easy but you have to do a few things before you head to the DMV, as mentioned above by others. You will need to weight and smog the truck. The dealer mailed the paperwork to the DMV location of my choice. At the DMV they will ask to see the emissions sticker (located under the hood), smog certificate, weight certificate and pay any additional fees. Around the time I was purchasing the truck, I had read that the window sticker must state CA emissions included, that was not true. Hope that helps.
