Don’t need it on the sticker. Just bought one out of state a few weeks ago and literally passed smog today in California. The only thing the stops you from being able to buy it without emissions being stated in the sticker is a dealer unwilling to take a risk that isn’t there. If you are a little paranoid, which is natural considering the price of the vehicle, have him take a pic underneath the hood of the truck with the emissions sticker.
Thanks for the helpful info, @OP can you send the pictures under the hood?
