That sure seems odd, I wonder why they had such a low payload and GCWR rating? That's lower than my old F250.

Regardless of that, the truck has plenty of rear tire/axle capacity and will safely tow 15 - 20k with a 4k pin no problem.

That 2008 quad cab 4x4 dual rear wheel had 12,200 pound gvwr. 21,000 gcwr. With the 6 speed manual it either had a 3.42 rear end or 3.73. If it's 3.73 (most likely) then it's the 21,000 gcwr. Only the automatic was available with a 4.10 rear end. Not sure why though. Just looked up on the ram body builders guide. I think what smokey was looking at was single rear wheel.

I know that 1 ton dually trucks are pushed beyond their factory numbers all the time. If it's just a matter of gearing then I could swap to 4:56's or 4:88's.
I am more concerned about braking and overall control of the combination. I am doubting that the new models are really that much more capable in real world service over a 5 or 10 year old model.
I am also looking at brand new "cab and chassis" 4500 / 5500 Rams as well as F450's & F550's. I would then have to buy a new flatbed for the new truck.
My wife told me that it only takes money! (I'm known to be rather frugal)

Rear GAWR 9,350 lbs. (Rear curb weight 3,226 lbs.)

Front axle capacity 5,200 lbs.
Rear axle capacity 9,350 lbs.
Front tire/wheel capacity 6,390 lbs.
Rear tire/wheel capacity 11,340 lbs.
Towing capacity 11,050 lbs. ( Stick shift lowers towing capacity to a max trailer weight of only 11,340)
GCWR 19,000 lbs. (minus 7801 curb weigh = 11,190 max trailer weight)

So no, that Ram cannot tow a 20k trailer. Maybe a 4500 Ram chassis cab, but not a 3500 DRW pickup.

2008┬*Dodge┬*Ram 3500 Specifications
These numbers are NOT correct.

Assuming it is has 4.10, GVWR is 12,200. GCWR 24,000. Max trailer over 16,000.

My truck handles the MS in pic with ease and is within front/rear axle capacity and combined weight ratings. Trailer weighs 23K and pin is at least 5,500#. Truck has factory rear air ride.

Analyze the specs:

Rear tire/wheel capacity = 11,340 lbs.

2,835 pounds per rear tire. That is exactly the max weight on the stock size tires 235/80R17E @ 80 PSI when mounted on dual wheels. When mounted on single wheels the max weight per tire is 3,085. That's what Service Description 120/117R means.

Size: LT235/80R17
Load Range: E
Serv. Desc: 120/117R

So no, the specs I quoted are for the 2008 Ram 3500 DRW diesel with manual tranny. I posted the link to the specs. If anyone claims higher weight capacity, then post the link to the specs for a 2008 Ram 3500 DRW with diesel engine and stick shift.

However, that link is to a car-nut magazine. I don't know if they made an error in their specs. But compared to a 2004 F-350 DRW, it's in the ballpark.

2004 F-350 DRW diesel:
GCWR 20,000 vs. Ram 19,000
GVWR 11,500 vs. Ram 10,500

No reason to argue about it. That's what the specs were back then. Then Ford upped the anti in 2005 model year, and again in 2008 and 2011 model years. Ram has been slow to catch up, but based on the internet buzz , they are close now.

Here's the link. Scroll down to quad cab 4x4 with 160.5 wb with cummins diesel and drw for dual rear wheel and you'll see its 12,200# and 21,000# gcwr. Look at m6 for six speed manual transmission. Irregardless he would still be over the rating but you might as well have the facts right.

You guys are posting numbers from the DRW pickup website when the truck is a cab and chassis DRW model with a ;
...12500 GVWR
...9350 RAWR
...5200 FAWR
...quad cab
http://www.rambodybuilder.com/2008/docs/dcdm/dcmlup.pdf

This website http://www.rambodybuilder.com/year.pdf
will give the OP numbers for the 4500/5500 cab and chassis for each year model.......and pickup models.

Brakes are a function of each GAWR.
With a 5200 FAWR and a 9350 RAWR = 14550 lb of braking performance.

A 20k trailer may have three 7k axles = 21000 lbs of braking performance or two 10k axles = 20000 lb of braking performance..
Now add them up and the combo has 35550 lbs of total braking performance.

This is one reason dot allows these size truck to run with those 30k-35k GCW plates. It has the axle/brakes/tires/suspension to handle the load if it operated at max weights.

Just wanted to suggest you think of something like an HDT. I know lots of HDT'ers and those trucks are great haulers. And a lot less expensive than a new pickup truck. I also think the cost to keep one running is less than a little p/u truck too.

Bad assumption. 4.10 axle was not available with stick shift. His is either 3.43 or 3.73 with GCWR of either 19,000 or 21,000.

True - provided he has the 3.73 axle. But with the 3.43 axle the GCWR is 19,000.

BTW, that was an extremely slow-loading website for my satellite ISP. But it finally showed up in my desktop.

How do you know it's a chassis cab? Lots of folks with DRW pickups replace the pickup bed with a flat bed. Including the guy next door to me that did just that to his Dodge Cummins 3500 dually pickup. Plus you can order a pickup without a bed from the factory, then have a ship-thru upfitter or your local upfitter add any bed you want.

So just because it has a flat bed installed doesn't necessarily mean it's a chassis cab chassis and not a pickup chassis.
