Maximum Trailer Weight Rating ?

[PUMPERDUDE]

What is it for a 99 QC 2500 Shortbed Auto with 3. 55 rear end. Owners manual doesnt list it. Does the Dodge Service Manual?

The "trailer tow rating" is pretty useless since it is based on a stripped truck (no options) with only a 150 lb driver. I'd suggest working from the truck's GCWR rating - on our truck, it can be found on the MSRP window sticker that came on the truck.

Here is the chart for the 2001's. It might give you some idea.

The Towing Guide in the 1999 sales brochure shows:



All Rams with the Cummins/Automatic 4-speed/3. 54 combination have a GCWR of 16,000 pounds.



All Rams with the Cummins/Automatic 4-speed/4. 10 combination have a GCWR of 18,000 pounds.



All Rams with the Cummins/Manual 5-speed combination have a GCWR of 20,000 pounds. *





*California GCWR with manual transmission is identical to automatic transmission GCWR rating.

Page 148 2500 Reg Cab Gvwr 8800 4x4 short or long bed not stated they go by Cab . trans auto, axle 3. 54 GCWR 16,000 Max trailer weight 9,800. Man. trans. all axle 20000 max trailer wt. 13,700 lbs. Ron Bissett in Metro Louisville KY :-{}

So the auto trans "trailer tow rating" assumes a truck curb weight of 16,000 lbs GCWR - 9,800 lbs trailer weight, or 6,200 lbs.



The manual trans "trailer tow rating" assumes a truck curb weight of 20,000 lbs GCWR - 13,700 lbs trailer weight, or 6,300 lbs.



Back to my point on trailer tow ratings - how realistic are these assumed truck curb weights? Also, notice that the "trailer tow ratings" completely ignore the truck's GVWR and the pin weight the trailer may impose on the truck (a huge deal with a 5th wheel!)

To illustrate your point, the guide in the 1999 brochure actually shows a Maximum Trailer Weight Rating of 14,200 pounds for the 2500 and 13,900 pounds for the 3500. I assume these are 2WD regular cab Rams.



The footnote regarding California Cummins/Rams noted above suggest that emissions also come into play since the torque and horsepower ratings is the same in 1999 for all manual transmission Rams.



Also from the table, all V-10 equipped Rams have a GCWR of 19,000 pounds regardless of axle ratio or transmission.

Looks like the magic number is 9800 lbs. Thanks for flipping through the book for me Ron.

Only if the laden weight of your truck with fuel, passengers, accessories, cargo, hitch, etc. is 6200 lbs!
