I think some are confusing the 'engine brake' on the earlier ford 6.7's with true exhaust brakes...

on my 2012 and 2013 it used the variable vane turbo to build compression (among other things) and make the engine a 'load' on the tranny,
I would like to see where you find that information. That is completely contradictory with the video that Mike Rowe did. It showed they achieved exhaust braking, by dumping exhaust into the intake to starve the engine. There was no use of the turbo until later model years (14-15). This is why Ford came in last in all the exhaust braking competitions with the BIG 3. I drive a 2013 daily for work.

The rule of thumb is to go down the hill at least one gear lower
than you went up the hill, towing a trailer is not a race to see
how fast you can get down the hill, it is how safely you can get
down the hill .....

I always start off the top of the hill slowly and as I progress I
tap the brake's every so often as soon traveling down the hill
but not laying or pressing down to hard on the brakes for a
long periods of time. This way you do not heat up your brakes
and it also keep your RPM's down.

WARNING if you keep braking on a say 6 or 7 percent grade by
the time you get two thirds of the way down you may not have
any brakes left. Do not waiting until the last second to
engage the "brake's " ....


We as the OP live out West an as he stated we have a ton of
mountains and hills with long grades .....

Using the Tow Mode has worked well for me and many others
as long as you use it the proper way .....Going down a 6%
grade that is 14 miles long at 60mph with a 4,5, or 6 thousand
pound trailer or more then throwing it into tow mode and hitting
the brakes hard is the fools way of driving ......be safe

Agreed. Only travel in the east, but have used this method on 6% grade in the Smokies and worked fine for me with our 39' Toy Hauler.

It's in the manual. Basically, in tow haul, if you tap the brake, you communicate to the truck that you are trying to hold the speed down. It then downshifts. Nothing at all like the current exhaust brakes.

agree

I have a 2012 F250 6.7 ... it's all transmission downshifting ... worked great with a 6500 lb trailer in the Rockies ... not so sure about my new 11,000 lb fifth wheel .... will be more careful about approach speed to descents.

In professional drivers manual (taking my CDL3) is says to "snub" the brakes moderately hard for 1-2 seconds several times to control speed and NOT ride the brakes - this will lead to overheating, and loss of control .... say hello to run-away-lane....YIKS

It is not just downshifting, there is an increase of back pressure to provide more engine braking. Of course a bit more engine braking each revolution is multiplied with higher rpm. The braking effect in the earlier 6.7's is not as great as later models, but it worked just fine with my 7,100 lb trailer in all kinds of mountains. You may need some brakes, but I'll bet it will be OK.

The stub braking is pretty much a relic from the past, just slow enough to reduce speed and the downshifting and engine braking will take it from there. Of course you will be using tow/haul mode.

perhaps ...

I KNOW that in Manitoba (Canada) we are living a decade or so in the past with MANY things ... this maybe so with the CDL ... but .... its in the exam and road test (so its taught ... by the way the closest hill from where I am is 3 hours away in NW Ontario... hahaha).

My 2 cents worth.

In PA there is still a tax on liquor to pay for the 1889 Johnstown flood.

There are some special considerations for trucks with air brakes, but how would conventional brakes benefit by jerking them on repeatedly? Just a feel good exercise in my opinion.
