So I'm a die hard ford guy and am looking at a 2012 f-350 with 36,000 miles on it. I'm just a little curious on the transmission issues with this year and the year previous. It's a 6.7 diesel and my first ever diesel truck. I'm getting a 30' camper soon and really like the truck I've been looking at but just a few concerns on it. Since its at a dealer with only 36,000 miles is that any reason for concern and how's the maintenance on these vehicles? I don't really know what to look for so any insight would be greatly appreciated. Sorry if this is the wrong section.
