Older reefers that have not been updated to newer truck style reefer units are banned from service in California due to emissions requirements so they are less usefull than they used to be, also, rates tend to be by the car and smaller cars hold less and are thusly less desired by shippers. There are still several locations that can not ship or recieve the larger cars so they are still needed for other uses outside of Calif. Also, some cars are reaching their 40-year rule deadlines and they may not be worth the efforts required to get an extension granted. If you need photo's, my advice is to get them now as the cars are on the endangered list.
