Weighed my truck last week

A year ago I bought a 2003 RAM 2500 pickup. It was clean and low mileage, but is a Tradesman model with rubber floor mat, crank windows and manual door locks. I don't mind I am used to that in my old Ranger (Ranger doesn't even have power steering!).

Anyhow, this truck has the 5.9L Cummins, 6 speed NV5600 transmission, 3.73 ratio 11.5 inch AAM axle, standard cab and long bed, factory tow package and hitch, 140 inch wheelbase. I also bought a nice Leer topper for it last year that even has a Thule roof rack.

The numbers from the cat scale at a nearby Loves,
Steer axle 4060 lbs
Drive axle 2860 lbs
GVW 6920 lbs

From the door label
Front GAWR 4630 lbs
Rear GAWR 6000 lbs
GVWR 9000 lbs

Factory hitch capacity is 10,000 lbs with 1000 lb tongue weight limit.

If you go by the GVWR I have a payload of 2080 lbs
However the rear axle can carry 3140 lbs and the front axle can carry 570 lbs.

The current trailer is a cheapie 2008 Thor/Dutchman Freedom Spirit 180 that has a GVWR of 7700 lbs, has two 3500 lb axles and will last me until the unicorns bring me a 25 ft Airstream or Bigfoot.

I seriously considered a truck camper, and with the Leer removed I gain about 200 lbs on the back, but the TC would have to be rather light.

My motorhome will be sold in about three weeks if the planets align. I have a solid buyer.

All I can say is dang, that Cummins is heavy. I knew the transmission was, 490 lbs of cast iron. The front axle weight of 4060 is exactly what the Ranger weighs leaving the scrap metal place with my 5x10 utility trailer behind it.

I read that the old Cummins engine weighed 1,300lbs. I imagine that is with all the stuff attached.

That is a heavy chunk of metal that the front suspension has to carry around. Watch the ball joints for failure.

Unless you have a recent PE in Chassis Engineering, don't try to outsmart the PEs that determined the max weight capacities of your truck.

Based on your numbers, the 16-year-old truck is a good match for the trailer. It has plenty of payload capacity for the ~1,100 pounds hitch weight of the loaded trailer. The limiter is probably the receiver hitch TW rating of 1,000 pounds. That means that you cannot load the trailer to the max of 7,700 pounds GVW, and loaded to have 13% TW, and use a good WD hitch that weighs ~100 pounds without exceeding the receiver weight rating.

Yep, all good diesel engines are heavy. My '99.5 PowerStoke diesel (PSD) was so heavy it had to have the optional 6,000 pounds front GAWR if you wanted to mount a RanchHand front bumper/Bambi deflector. And you don't want to drive in Bambi country without a good heavy duty Bambi deflector. Daughter was coming to visit us after sundown and Bambi went through her windshield and made a real mess of her car that didn't have a Bambi deflector. But my F-250 PSD with its heavy front end was a joy to drive when towing my 9,000-pound 5er.

I have the same truck '03 2500 quad cab short bed NV5600 tranny 3.73 gears 2wd with the 305/555 HO HPCR Cummins.
Mine is the SLT package with the same 2860 rear axle weight. However my trucks front axle weighs 4160 lbs.
I tow a 11200 lb 31' 5er since the truck was new. I also tow other flatbed trailers up to a 16 GN 36' tri axle stock trailer. The tri axle trailer when fully loaded pulls and stops easier than the smaller tandem 5th wheel rv trailer. I load the stock trailer to stay under the trucks 6000 rawr. For whatever reason Dodge didn't have a aux upper overload spring pack for the new '03 3rd gen and up 2500 trucks. Now my old 2nd gen 2500 '01 had the upper overload spring pack and could carry a lot more weight without sagging.
Dodge gives my truck a 13250 tow rating so these trucks are made to work.
My '03 has 315k miles and is in top shape. The '03/'04 305hp/555 torque HPCR Cummins gets some super mpgs running empty or towing.
I had a Jacobs exhaust brake installed when new as part of Dodges Businesslink program. Best by far option I've put on a diesel truck.

The old 12 valve like I have weighs 1,100 dressed and my truck is 6,800 pounds. Haven't done axle weights, just total.
