You do understand that all the braking from an exhaust brake is done thru the rear wheels of the truck? That heavy truck and trailer is pushing on those two tires, and everything else is going along for the ride.

All 6.7 Fords had exhaust braking as claimed, previous engines had none and there was no claim that they did. Yes, later models had more braking and a button to play with.

I understad all you are saying ,just didn't get you saying I have more tires then me. I have a SRW 3500 Ram Cummins . As said yes ,Ford had no exhaust brake in the earlier Powerstrokes, I am aware of them having one one now , have read many times ,they were no where near as effective as the Cummins , it sounds like they have finally caught up , which is great. I know the benefit of having a good exhaust brake while towing. , or anytime . I run with tow haul ,and exhaust brake on regardless of what I am doing, unless there are slick roads .

Its good to hear the Ford has caught up with a effective exhaust brake ,my son has a new 2021 on order, and plans to be towing a fifth wheel.
