The 2015 DURAMAX with the cruise on and in tow/haul, pulling the fiver, will keep it close to set speed. It usually kicks in when speed hits 3 mph above cruise setting and then backs the speed down very effectively. It also kicks in without towing.

I have a '14 Ram 2500 with the factory EB. I love it! Works great weather I'm towing or not. 1st real use was on Memorial Day weekend. We went to Palo Duro State Park (Amarillo, TX area). I believe the grade down to the canyon was 10%, put don't quote me on that! I never hit the brake or the accelerator and traveled down into the canyon at 20-25 MPH. Well...., I exaggerate a little bit....there were some 90 degree turns that I had to negotiate, but I was glad I purchased the truck and wasn't still using the wife's SUV!

I thank everybody for the responses. I drove all three, Dodge, Chevy and Ford. And like I said, none of the salesmen had a clue, so there's a good chance the EBs weren't engaged properly. I will say, while I grew up on Mopars, the cars stunk in the 70s and I went to a couple Chevs and GMCs before switching to Ford. It may be time to take another look at the Ram, although the Glory Guts Ram phalic commercials make me cringe.

I chuckled at the "lesser trucks" comment. I can not speak for the Ford or Duramax trucks, but the exhaust brake on my Ram is pretty awesome, loaded or not.

On a side note, current Ram/Chrysler/Dodge products are not the same as in the 70's by far. Interior of my Ram is every bit as nice (and nicer in some aspects) than the Chevy or Ford trucks, but that's a matter of opinion.

Ignore the commercials, let the truck speak for itself.

Got my first experience using it with our new 351RSTS (15,500 GVWR) and I really like it. Used in conjunction with the Tow/Haul mode, there was a noticeable difference in control on steep declines. After just a few minutes of turning it on/off, I really felt it was a big help so I just left it on all the time.

Last Sunday we returned from LA via the Grapevine (I-5), with the combination of the exhaust brakes and in tow mode, we hardly knew the trailer was back there. Very quiet and I felt extremely safe!

[The Grapevine was infamous for its high accident rate before the road was straightened and widened. There are escape ramps branching off both sides of the downward part of the road for heavy trucks whose brakes fail on this very long, 6% steep and now straight grade.]

The EB on our Duramax has a very noticeable difference towing or not even with tow mode not engage.

The EB on my 2012 works great, but is far more noticeable when towing a load. My EB will even slow TOO MUCH without the cruise engaged. The newer Rams have an improved EB with two stages.

You have to try one.

I have a 2011 F250 Ford with 70,000 miles on it. Checked the brake pads during the last oil change. There is virtually no ware on the the pads. That is a direct testament as to how well the transmission brake works. Im sure all manufacturers are close on this technology but the Ford takes all stress out of steep long grade changes. The transmission is very, very intuitive when in tow mode. I rarely ever touch the brakes in the mountains.
