The Dumbo mirrors are nice, but the built in Ford brake controller is what I really like. Much more integration with what the truck is doing. No more jerking when going at low speeds. I understand it is not an inertial controller like the after-markets but get's its info directly from the truck's brake system.

One more thing I've heard about about hauling heavy loads up steep grades: Premium gas may be helpful, especially when it's hot.

Enjoy your truck.

 

The standard mirrors are ok, nice and big but I think the length of the trailer really limits them. My TT is 30' and I can't see cars that are close behind me like I would with the towing mirrors. I can see down the side of the trailer just fine though. I do miss having the the small "blind spot" mirror at the bottom of the towing mirrors as I like to see my trailer tires if possible.

 

I have been up a few steep grades but none that ascend 18 miles I still think it will be no problem for the truck. Like others have said, use premium fuel when towing and let the tow/haul mode do it's job and you should be good to go.

 

6% grade, 7500# travel trailer, three miles, 55mph, 105 degrees outside.

At that speed, she was turning 2400 rpm in fourth gear. Coolant Temp stared raising and got as high as 228 and was still creeping up. So I dropped back to 45 mph and temp rapidly dropped back to 205.

Moral of the story? Water cooled turbos eventually will raise coolant temp it's hot enough outside.

Granted, 105 temp outside was way out of the normal. That same drive I normally don't get any higher than 205-208 with temps in low nineties.

If you take it easy, you have more than enough motor.

 

If it's on internet, it must be true . . . .
