I don't know what grade the hill was that he was pulling but to pull a 14,000 lb trailer up a steep hill at 110 kph takes a lot of power. He was comparing a 385 HP Ram to a 500 HP Ford.... and he says it didn't pull as well on account of the 6 speed transmission,:S.
OK, explain why he had only 22psi boost? IdaD wrote:

I'm half your age and think speed up a hill towing among any of the diesels has been a draw for at least a decade now, if not more. The exhaust brake is an area Ford and GM can still meaningfully improve, imo.
To me speed equates to towing performance or said another way towing comfortably. Like I always said... Towing Got Easier :B- 4x4ordExplorer III^^^You can call it programming or whatever but it comes down to power.

- Cummins12V98Explorer III22psi "FULL", I don't think so. No wonder it did not maintain 68mph. It's all about programming, it could have delivered 30psi if the computer allowed and maintained speed. Trans had little to do with this as he was in high enough rpm's to pull well.
For a couple mph loss I will stick with total control of my load on descent. - Cummins12V98Explorer III

I agree with you there about the exhaust brake. Ram has always been strong there. But that being said, I have a friend who runs a 2020 SRW F350 with a Jayco Pinnacle. He stated on his way down Black Mountain (NC) all he had to do was set the exhaust brake to auto and he never had to touch the brake one time. It held a constant speed all the way down.
I'm not 100% sure how that auto setting operates but whatever he did, I'd be happy with that result.
It all depends on the grade and weight of the RV. My 24k RV plus 1.5k MC trailer and Bike require full EB and setting cruise at lower than desired speed. I can descend any West Coast grade without a single brake application but I need to be in the correct gear for the grade. - JaxDadExplorer III

As a kid learning to drive trucks one of the very first thing the ‘old guys’ taught me was “Don’t chase the governor! It’s hard on the truck & the driver.”. Those words have served me very well over the decades since.
Ontario is pretty flat in this area, just some slow rolling hills and pretty gentle grades, but this is such a massive place that if you venture further out you certainly get into some serious grades.
Generally the only ‘mountains’ that I have to run through, although I can mostly go around them, are the Appalachians on the frequent north / south runs.
In my own rig I’ve found the ‘sweet spot’ is about 68 mph (110 km/h) and if I can hit the bottom of the hill at that speed or a smidge more it makes a huge difference in how much speed bleeds of in climbing the grade. I figure everyone else is in the same boat and we’ll all get the lost speed back on the downhill run after cresting. lawnspecialties wrote:

The "auto" modulates the exhaust break to maintain a specific speed and the "On" position is full exhaust break and try's to slow down the vehicle.
Having said that, the cummins does have the strongest exhaust break.- lawnspecialtiesExplorer
