don't forget the towing mirrors that came on my 3.73. Those things are the bomb...except for parking.

Towing the longest and steepest grade ever, 9 %, Trans Temp went to 95 C with my foot down at 60 mph. The Engine temp never peaked at all.

I haven't pulled that steep, but I don't notice much change in temps when towing either. It's like it reaches operating temp and stays pretty much there, or within 10 degrees or so.

They are definitely the bomb. I had them installed when I bought my truck.

Didn't you get the power folding ones? Maybe this is a difference on the King Ranch model?

Shoot when I get ready to park our EcoBeast, I hit the switch and fold those suckers in and use the cameras

That is really good to hear Brian! We were concerned that, when we retire and tried to pull our unit through the Rockies we would regret not having a diesel.

When we got our '13, the 3.73 was the only option. Shame, this must be why you get better gas mileage than we do.

We get 19-20 Highway, 15-17 City, and 9-10 towing the Rockwood 5er. Bummer is most of our non towing driving is city

As I understand it, they didn't come out on the F150 until 2013. I was bummed. If I could add any one feature to my 2012, that would be it.
