When towing always keep it in tow mode. Also drop it back one gear normal drive and leave it there.

Also, I don't believe a 2013 has 400hp. But could be wrong.

Yep, like Marty says you're bumping up against the laws of physics. The 2013 is rated at 400 hp but it's not putting that much to the ground. People like to crow about how their rig can "pull 30K up a 6% grade at 80 mph" or some such nonsense, but typically they are fibbing about the weight, the grade, or the speed, or all three. To give a basis for comparison, a semi I sometimes drive weighs 30K empty and pushes a similar frontal area to your combo. Hammer down, it will pull a 6% at 60 with a good run at it, and it has 10 speeds, 515 chassis dyno certified horsepower and over 1500 ft.lbs of torque. Loaded to 72K it's more like 40, and that's not bad. So if you're getting pulled down to 50 or so on a 5% grade weighing 25000 lbs combined, it's not the truck, it's just math.

Sounds like Travel1234 was still trying to use gears 5&6 when they should have stopped upshifting at 4. Lol.

Wait until you are in lowest gear, full throttle, and still losing speed.
That is when you start to worry.

The actual problem is circled right on the grille and highlighted in blue!
(Ducking for cover now.....)
And yes I know what part of the female anatomy a Ram logo supposedly looks like, although I think that means other owners who point that out are pervs! lol
