Need help with GVWR (Was Holy Cow !!)

I am so darn confused. I for the life of me cannot seem to figure out how much over weight we are for our TV ??
Please if anyone out there could give me some idea of where we stand I would be ever so grateful. I have a headache from trying to figure it out. I read all the posts and I am still too stupid to get it. Took the truck out to weigh with full fuel and me.
This is what I got at the CAT scale.

Steer Axle 4720 #
Drive Axle 3460 #
Gross weight 8180 #

Went back and weighed with 5er partially ready to go. No food or clothes yet.

Steer Axle 4800 #
Drive Axle 5820 #
Trailer Axle 9940 #
Gross weight 20560 #

Thnx All
Jo

Trailer weight = 12,300. Compare to GVWR of trailer.
Truck weight is 10,620. Compare to GVWR on truck.
Truck rear axle is 5,820. Compare to RAWR on truck.
A single trailer axle is 4,970. Compare to axle rating on trailer.
Combined is 20,560. Compare to GCWR for truck/trailer combination.
You have a 20% pin weight which is average.

The airbags will level you out, but give you zero in extra capacity.

What is missing are five very important numbers you should know.

The GVWR of your TRUCK - Door sticker or spec sheet
The Gross FRONT Axle weight rating of your truck - Web or Spec sheet
The Gross Rear Axle weight rating of your truck - web or spec sheet
The Gross Combined Weight Rating of your truck - web or spec sheet

and the Gross Vehicle weight rating of your camper. Yellow sticker on camper.

Please post if you can get those numbers as they vary from model to model of your truck.

Ok, I found the GVWR of your truck right away. I will keep looking for your Combined weight and max axles loads. Remember the curb weight of your truck is the GVWR minus your cargo capacity.

The Gross weight of your truck (the maximum IT can weigh with you, your family, your hitch, your pin weight, and all your gear is 8800 pounds.

From your door sticker it says your max cargo load is 2244 pounds.

Subtracting 2244 from 8800 should give you your curb weight with the diesel engine or 6556 pounds. That is JUST you (provided you weigh 150 pounds) and a tank of gas.

So working with the 2244 pounds of "Load"

Subtract from 2244 the weight of your hitch - maybe 144 pounds
Subtract from 2100 the weight of wife and family 300 pounds
Subtract from 1800 pounds junk in truck like cooler with beer 100 pounds
Leaves 1700 pounds available for pin weight.

Looking at your numbers, it shows you seriously overloaded. Time to trim back on what you are taking. If no camper you weigh 8200 pounds then you only have 600 pounds available for the camper. As you sit, your truck is weighing 10,620 pounds with the camper on its breaking back.

10,620 - 8800 = 1820 pounds overweight on the truck.

Your trailer as currently loaded weighs 20,560 - 8180 = 12,380 pounds which is under its max of 13805.

Your pin weight is 10,620 (after camper) - 8180 (before camper) = 2440 pounds.

Your problem is pin weight on the truck. Now, having said that, many will tell you your truck can handle it. Maybe they are right, but Dodge seems to think not for some reason.

Lou, his truck should weigh more than that, I was at the dump transfer station a couple of days ago, little more than a half tank of fuel, myself and son (220# combined) and the weight on the scales was 7650#, very similar truck configuration, after I dumped the yard trash. (empty bed)

Ok your GVWR is 9,600 pounds according to the sidewise sticker (hurts my brain after several glasses of home made wine).

Front axle ok at 5500 pounds -> your load 4800
Rear axle ok at 6010 pounds -> your load 5820

Your frame is what is overloaded at 10,620 by about 1000 pounds according to Dodge.

Actually it is his springs which are overloaded. 2500/3500s have the same frames, the difference in GVWR is the springs, tires (single or dual rear wheel) and possibly the rear axle (there is some debate about this and I am not up to date on the 4Gs).
