That is pretty impressive for the Ford running 3.55 gearing. The 10 speed seems to be doing its job.

Don't understand why you would start downhill with 30K behind you and not have exhaust brake on.

Well they stated on auto setting, I know Ram has Full and Auto. I run full when not towing, and auto when towing and using tow/Haul, that combination works very well at holding speed.

They started just using cruise control and said it gained speed. They had to hit the brake and then used auto engine brake setting. The Ford has 2 settings for the engine brake, manual and auto. Manual gets more aggressive every time you touch the brake, and auto holds the speed when you lift off of the go pedal.
