Lots of experts, my experience with exhaust brake is if you towing over 16,000 lbs and don't have Disk Brakes on the 5th wheel you will probably need the exhaust brake. But there are thousands towing without the exhaust brake and using the electric brakes system. Don't know anything about Dodges or Fords I do know that the GM Trucks with the Duramax/Allison you don't need a exhaust brake the Allison will do the job. I wouldn't spend the money on a exhaust brake but would upgrade to Disk Brakes for the 5th wheel, much better use of your money. And yes the 2006 Chevy Kodiak 4500 did have a exhaust brake from the factory. GBY....

After several years of class A ownership, I'm moving to a fifth wheel (10500 dry), pulling it with a 2003 Dodge 2500 diesel. I had great experience with my exhaust brake in my class A but wondering if I need one for my next rig. Do some mountain driving in Colorado and some of those grades can cause a little pucker to say the least.

Any thoughts would be appreciated.


Seems as tho someone is hyjacking the OP thread about his Dodge/Cummins question and has turned it into his own DMAX questions.

The OP is asking about a '03 Dodge/Cummins and the need of a exhaust brake.

To the OP. If your trailer is 10500 dry then your looking at around 11500 to a possible 12000 lbs.

I personelly wouldn't be without a EB with a Dodge/Cummins with the 48RE or 47RE or 6 speed manuals which ever the case may be from your year model truck/tranny.

My first Dodge/Cummins was a '96 3500 DRW that I bought used. It had a B-D exhaust brake. I bought a '00 2500 Dodge/Cummins with the 47RE and had a B-D installed when the truck was still under warranty just as many other 47RE owners have done with zero issues.

My current truck has a Jacobs as it came with a Dodge warranty. Its been flawless for 165k miles. If I was going to put a EB on a used diesel today it will be the Pacbrake PRXB for two reasons.
#1, although all EBs have around 180 hp for braking the Pacbrake PRXB has more braking power in the 1500 to 1800 rpms than other competiters.
#2 reson is as others have said the Pacbrake PRXB works from air pressure, unlike the Jacobs which works from a vaccum pump. The air pressure pump can be used as a air pump for other things as has been mentioned.

I would make a couple of trips and see how your particular truck handles going down those long steep grades. Then make a decission based on your experience.

I have the Pac-brake installed on my 07 Dodge 2500 5.9 AUTO Mega cab 4X4. Fully loaded I'm right at 20,000 lbs.(truck and trailer) with my 30' Wolf Pack 30wp. The Pac-brake makes all the difference in the world. I won't tow without it now. Heck, I use it around town without the trailer. I wonder how many years I'll get out of my pads? They are used rarely.
