5.9 Cummins Diesel Towing capacity

Yeah, get a newer truck with a higher towing capacity.

Either a different trailer of a different truck.
Or ignore the numbers as so many do.

What year of truck?

Go for it.
However we need more in put on what year model and is it a DRW or SRW. Older SRW with 17" tires and wheels (6200 RAWR spring pack) may need some rear suspension/tires and wheels help.
If its the older 47RE it probably needs some good uprated innards made for towing heavy.

I wouldn't worry too much about the towing capacity. I'd be more concerned about payload, tire, wheel, and axle ratings, and if you'll need some heavier springs or air bags. The extra 1,000 pounds isn't really a big deal.
I would want the manual transmission in that truck. Dodge automatics were not the best and you'd only have 4 gears anyway.

Any ideas?

I have a 2001 Dodge 3500 diesel dually. I pull a 5th wheel triple axle toyhauler that weighs a touch over 15,000 lbs. The engine has been fiddled with, and the NV5600 has a new clutch, but the truck pulls very well. I have to keep an eye on the pyrometer because it's very easy to get too enthusiastic with the go pedal and the temps can get very high with injudicious use of the right foot.

I pulled a 35' 5th wheel before this one and it weighed about 12,500 lbs. The truck pulled that thing with no issue at all, and got around 11.5 mpg. And that was with a basically stock engine.

Well a few questions;
What year is the Ram, in 2003 they went common rail and gained close to 100 hp and about 200 lb ft of torque.
Is your 3500 DRW or SRW
We towed 12,500# with an 2001 Ram 2500 with a small chip without issue.

Is 14,000# the 5ers dry or GVWR, if dry you might have an issue, if dry it depends on how much you add to it.

Not enough info so why even give a half AZZ answer?

OP fill in the blanks.

The rig your looking at is 14,000 dry? So like 15-16000 outfitted?

it is a 2001
5.9 diesel
Dually
not 4x4
I had the tranny rebuilt with very heavy duty inards. He said better than the original and an extra cooler
Also has been chipped,
I never have had the the radiator flushed or the fluids changed
So I was pulling a 12000+ 5vr and it did find on the level but climbing a steep pass like a 2 lane and it got real hot so I pulled over 3 times to let it cool.
If it hadn;t heated up I could have pulled over that pass and others without any trouble.

The issue with the 2001 is the puke bottle getting gunk on the back side of the radiator. Drain cooling system, and pull radiator and steam clean all the gunk off of the cooling fins. Then refill after internal flush with 60/40 antifreeze/water mix for max cooling.
