Tips on using Tow/Haul mode for engine braking

We'll soon be doing some driving through some North Carolina mountains and I'd like to brush up on tips for using the engine breaking feature in tow/haul mode.

I realize it depends on the downgrade, but generally speaking does simply engaging the tow/haul mode provide sufficient engine breaking on most grades or do you find it's necessary to shift to 3rd, or even 2nd, with the tow/haul engaged, to get adequate engine braking?

Appreciate any thoughts.

On our 2013 Ram that has both the T/H and EB features, I have never found it necessary to supplement the EB to feel comfortable when going downhill.

We just set the T/H and EB together and go.

The only time I have used the downshifting was coming down from Pikes Peak and obviously we weren't towing our FW then.

The tow haul method is very good for the mountains and provides excellent downshifting for the motorhome, especially when towing..we use it whenever in the mountains....

While going through the Big Horn Mnts. in Wyoming recently, I found that I didn't like the T/H mode in my 2012 F150. Going both up hill, and down, it stayed in a lower gear longer than it needed too. Just wouldn't shift. RPM's were too high. Trans temp shot up 20 degrees. Turned off T/H and much better. I haven't used it since. I think the wind resistance alone is enough to slow me down.

I use the tow/haul feature all the time when towing our HHR with the Georgetown. I find it is very effective in selecting the correct gear both up hill and down. On steep downhill runs a touch of the brake pedal will bring a downshift (if needed). I have never needed to manually select a lower range even in the steeper western mountains. On uphills the V-10 likes higher rpms, and the transmission keeps it in the correct gear.

I use it all the time on my F150. As Ohiobill said, on downhill runs just tap the break and it downshifts. Holds the speed without using the breaks.

I use T/H whenever I'm pulling the Jeep. As previously stated, just a tapping on the brakes gets you a downshift. I spend a lot of time driving in the eastern sierras here in California. My previous motorhome had the older V-10 with the 4 speed and no T/H mode. It was a lot harder to drive in the mountains and required a lot of manaul gear selection that I don't have to worry about with this one.

I use both and usually never touch the brakes and there has never been a need to manually shift down to control the speed. We even went down a 14% grade in wy without problems. Though had a known it was straight down I would have looked for another route!

Is that the pass west of Jackson Hole WY driving over the Grand Tetons Pass I think it was route 31/33.
That one is about the same grade only 10% up and down grade but felt like 14%. Only went west to east and never do that again. Yes I did you my Tow Haul mode as well as learned to respect the Ford V-10 and chassis.
Next time I will will go south around the mountain even if it is 50 miles more .

Coming out of Fishing Bridge in Yellowstone heading east to Cody is the steep road I mentioned but the Grand Tetons will get your attention as well! TH and engine brake are awesome in my Dodge 3500.
