I purchased my new '13 F350 6.7L a couple of weeks ago. I did not have to sign any document that was referenced above. I've been a GM guy my whole life, but switched to the Ford because I just liked it's appearance and features more. I liked my previous Chevy trucks, and don't have anything bad to say about them. My '04 had nearly 140K miles, and it only let me down one time with a failed fuel pump at 98k miles. My wife and I will be hitting the road after the first of the year for some extended travel when I retire. I'll keep posting on my experience with the F350.
