This is the correct answer.

I concur. But people need to understand that is NOT a 5er as the pin weight will exceed the RAWR. Most likely a gooseneck is what is tested at 18k.

Last time I checked a gooseneck hitch was still a bed mounted hitch. so it still needs a higher % of HW vs a ball or pintle which can be less....

Still the issue with the J2807, is the performance specs, if something meets the absolute minimum, ie the 12% grade, you will/may not be pulling a 14% grade. most of us pulling 14% grades, are not going faster than 35-40 mph! Not does one plan to go faster than this! Even the 18% grade in front of my sisters house, I do not plan to go much over 25-30mph, granted a residential road......or the 25% grade on the north side of Queen Anne here in seattle on Queen Anne ave! doing 25 mph you are doing good!

Question what you would be towing that weighed 18k? My question is can the truck HANDLE it???

I tow a 23k 5er with a 2k motorcycle trailer behind totaling 35k with ZERO EGT or overheating issues. Even on grades up to 14%. Sure mine is a Dually but the engines are the same.

Cummins was able to tow uphill the trailer wihtout any problems. Great truck!

The ram 2500 Cummins ctd has towing capacity of Almost 18,000 pounds.


Is that on flat roads Only?


How about towing uphill? Will it still be 18,000 pounds?

Lol, yes. But not in the rain on a Mountian......

Not sure what the OP is going to be towing? My Ram 2500 diesel will pull our TT loaded (8,000) up the Grapevine without slowing down with no trouble at all.

As typical of this forum we like to look at one parameter and ignore the others. The tow ratings are genuine but you must account for the other parameters such as frontal area, and payload as well.
Pay attention to all of the ratings not just the ones that work for you while pretending the others don't exist.
The tow rating alone does not tell the whole story.
All of the physics and factors involved cannot be expressed /quantified in one rating. As a result there are multiple ratings to consider

Maybe same engine but not same gearing.
Frank,

Gears might not be as big a deal as what you think. The Ford towing numbers are:
the F250 tow rating is 14700 lbs
F350 srw tow rating is 20600 lbs
F350 drw tow rating is 27300 lbs

All three trucks are rated with the same engine, transmission and rear end (3.55:1).

Towing Capacity numbers are not real world numbers.
They are from towing in perfect conditions and with something that offers very little air resistance.
That way they can inflate the numbers.
