Down hill pull question

I have a 2005 Dodge diesel 2500, I am pulling a 6500# bumper hitch trailer.

we are going to the mountains (NC)this next week, driving from west KY>

I like my dodge diesel and it pulls my trailer great.
but, I am very concerned about the down hill (mountain) pulls that I am going to have to make.

my truck does not have an exhaust brake,

a 2005 dodge diesel transmission only has 1,2,D and you have tow haul on the end of the shifter.

QUESTION:
when I start down a long mountain, what gear selection do I make, what is going to help me hold that load back???????????

I have heard that the diesel engine has little to no braking ability, so do I just ride the brakes until I go over the mountain side when the brakes get hot and go,

as you can read into my posting, I am somewhat concern about this.

I just bought new tires and shocks for the truck, I may have been better served to have purchased an exhaust brake.

but, have heard the 2005 dodge diesel transmission does not like exhaust brakes so well.

can any of you, that has pulled with a 2005 dodge diesel give me some pointers on how to handle the load.

seems like trading the tuck for one with an exhaust brake or not going are not options at this time.

My friend will also be traveling with us, he has a 2010 gmc 2500 diesel and he is pulling a heavy, hitchhiker 5th wheel, but I do not think he has an exhaust brake either. however, he has the Allison transmission that may give him better downhill control.

Thanks for any and all responses, as you can tell I am a bit worried.

    Your truck will have no problem holding back a 6500 lb trailer without an exhaust brake on highway grades. If you ever get on a very steep grade that requires more wheel braking than you are comfortable with you can downshift manually, then slow with the brakes until the transmission makes the shift or start in low gear from the top.
  • You seem to be overly concerned about something that should not be an issue with a trailer that size providing that the trailer and truck brakes are in good shape. Think before you start down large hills. The lower the speed and gear that you start in, the better control you will have throughout.

    Personally if I had that much concern about the capability of my truck with a load that is way below its designed capability, I would probably upgrade the truck.
  • Run it in D and tow haul. Down shift to 2 or 1 as needed. The mountains in NC are not that bad. Your friend will only need to tap his brake petal a time or two to downshift. He will love his transmission.
