Just ordered a 250 lariat gasser. The sales story this year from one dealer is that the snow prep adds a bigger fan for $80. The 200A alternator was included in another pkg I got. I guess that they are selling as many as they can make otherwise they would make the selection of options less secretive. I finally went thru a broker because he was the only guy I could find that even pretended to care what I wanted and bothered to research questions and get believable answers.
