I went the AZ route instead of Nevada, and ordered the truck, and I'm pretty sure I remember trailexplorer saying he ordered his. I just got off the phone with the AZ dealer I dealt with and he gave me what should be pretty good info.
When you order a truck, you give an address... . they even wanted a photo-fax of my ID. They got a CA address from me. When he's running down the list of options on an order, there is a check-off on Calif emmisions. It is the dealers responsibility for that check off if he is ordering a truck for CA. Once that's done, the rest is automatic, and when the truck arrives you gots your sticker that says it "conforms to California regulations for the 200X model year". This is on the valve cover sticker. You HAVE to be a border state to be able to order it. When I picked up the truck, I had him point it out to me so I knew I wouldn't have any problems. If the truck is ordered this way, I'm figuring the responsibility is on the dealer and that's where recourse is. An interesting note is that he had a driver & I go to the border together, and in front of a notary, we actually had the change of possession take place in Blythe, CA. I didn't ask, but I'm guessin' there is a very good reason for it. This dealer advertises in SoCal, and does a good business here, so he's had lots of practice. He was also 1700 less than the best deal I could get in SoCal, so a $100 plane fight was a no-brainer.
If you pick it up off the lot instead of ordering it, you would probably run these kind of problems, but then the guy I bought mine from said it would be the dealers responsibility to find out the destination state and not sell an illegal truck.
Now the funny part... I'm waiting for my ownership paper from the dealer so I can register mine

... 'cept everything I heard also checked out with what AAA told me, & they've seen the truck and they said 'no problem, we'll do it all here (in their local office vs. DMV ), as soon as the title document comes.
This is the kind of headache no one needs, and I'd be lookin' to sort it out right, just in case some vehicle inspection down the road turns out to bite you in the ask me no questions and I'll tell you no lies. ( not that I have resorted to lying or cheating in some past life getting a 70 F250 through smog or anything ). Keep the dealer responsible through registration until it's right. I'm sure dealers are under legal obligations when it comes to something as heavily regulated as the automotive industry. Just an opinion though.
