From what I gather over the past few years, the only unreliability of this truck has been either engine failures, or rear gear failures as common issues. There was the converter pressure valve that came loose last year, but that's either a prep failure or just plain bad luck. None of which I believe have to do with the layout design of the truck itself, I don't know why everyone points to the layout of the truck being the cause of reliability.
Mason went with this same mid-engine layout for a reason. They are smart people, I am sure there is plenty of weight up front to get the front wheels to pull.
