The only problem I had with my '12 was when it was about 6 months old and the A/C stopped cooling. The evaporator had to be replaced. No other problems with the truck. So far the '15 feels to be more refined and quiet than the '12. Transmission shifts smoother and the engine has an incredible amount of power. Probably be another week before I can tow with it but I am looking forward to it.
A few interior shots. Also checked out the size of the tie rod and steering components. I had read that Ford was beefing up the steering and drivetrain, looks like they did.
While I know a lot of the modern 3/4 and 1 ton, diesels can easily, but not cheaply, produce the same power, none are built as heavy duty as that one, from the factory. The drive train on that beast really qualifies as HEAVY DTUY! Nice truck.
