We have a 2012 dodge 2500 crewcab gasser with flatbed hawk. Seems the benefit is when on cruise control at speed going up rolling hills the engine drops rpm and speed that a much lower gear is selected with way too much throttle to try to bring the set speed back.

At the bottom of a hill that I think the cruise can't handle I press the tow haul button, kicks down a gear, raises the rpm a bit a runs the hill just fine.

To note I can press to engage and then press to release. The setting will stay engaged until the top or load is not needed any more.

Have not noticed any other advance. For downhill doesn't seem to kick in to help slow down.

I use tow/haul when I feel the transmission shifting a lot, trying to find the right gear.  Or when, from experience, I know the transmission is going to start trying to find the right gear.

 

2012 Ram 2500 + Grandby: about 8000 lbs loaded.

I use tow/haul on steeper hills so the transmission doesn’t keep looking. On steep downhills I also use it in conjunction with the exhaust brake. I have a Ram with the Grandby.

I use it regularly with my 2010 Tundra. Most of my driving is up and down mountain passes, I like the shift pattern going up hill and the braking/downshifting it provides going down hill. I will turn it off for long, flat stretches to help with gas mileage.

2021 Tundra with ATC Cougar camper. i use the tow/haul on long grades over passes, but that is really about it. it certainly does help with the power for pulling a long grade.
