I just love when all the Ford owners insert their opinion about what tow haul does on their truck, even though we're discussing Ram's.

Discussing Hemi's, because it's different for the 2500's. Tow/Haul doesn't just deactivate the MDS, but alters shift points. Motortrend called it the closest thing to a "Sport Mode" in a truck. As I can assure you from experience, Ford & Chevy's tow hauls do not have the same radical changes the Ram's does. Ram actually loads a different fuel curve and adjusts torque management in the transmissions along with shift points which shift firmer and hold longer. Also, engine braking, yeah they Hemi half ton does engine braking too.

Gasoline engines brake well by nature because they have a throttle butterfly, but the engine brake function has to be added to a Diesel. Different animal.

I agree - hate tow haul mode on when driving on flat land cruising

I just this weeks drove from Birmingham to Destin In plain non tow/haul and watched trans temp - stayed just fine

In mountains I cut it on

I also cut it on when anticipating going from highways speeds to a stop ahead

I only see one, and that was back in February...

It seems to me that the computer could sense, based on engine load, whether tow/haul is necessary and engage it automatically. I've forgotten it, too.

So, when I tow my Airstream I push the Tow/Haul button before I put it in drive. AND, depending on the terrain, I also push the exhaust brake button. While this may not work for everyone, I'm at 21,000 miles with a '14 truck. 19,210 of those miles are towing -- I know, because the truck keeps track of that IF the "Tow/Haul" button has been selected. I LOVE my Ram 2500 and that big honking' Cummins!
+1 Always use Tow/Haul Mode when towing and I use my exhaust brake all the time unless it's icy. We are very happy with our Ram/Cummins.
