I'm looking at buying a used 2013 F350 DRW 4X4 and the GVWR is 14,000 lbs. But the Front GAWR 5940 lbs. and the Rear GAWR is 9750 lbs. and that adds up to more than the GVWR. How much rear payload can the truck handle?

I would be using it to haul water and also would like to mount a plow up front.

 

This is the door sticker for the truck

 

I'd say it can hold enough rear payload to put 9,750# on the rear axle with 4,250# on the front.

Or, if your plow brings the front axle up to 5,940# you could have enough rear payload to put 8,060# on the rear axle.

How much water that turns out to be depends on the curb weight of the pickup loaded with you, fuel, plow if desired, and an empty tank.

 

So, the 14,000 lb GVWR is the total amount of payload the truck can handle without going over either of the axel limits? It would have a 1000 gal water tank with a total weight of about 8,600 lbs. I haven't spec'd a plow yet but I doubt they are over a ton.

I thought I had to subtract the actual weight of the truck from the GVWR rating.

 

Yes, you have to subtract the weight of the truck. Don't forget your own personal weight and fuel weight. You also have to factor the weight of the tank itself, and then the plow too. An F350 is too light for your application. You really need an F550.

 

The axle ratings are higher than the GVWR to give you some leeway as to how you balance the load front to rear. You need to find out the weight of the truck now, add the weight of the tank empty, add the weight of the plow, subtract that from the GVWR and that is the capacity you will have for water. The GVWR - gross vehicle weight rating - is the maximum the truck is allowed to weigh. The payload is the difference between GVWR and what it actually weighs unloaded but with all your stuff on it.

 

Thanks

Now I understand why the sum of the front and rear limits are a bit higher than the GVWR. I can put the water tank on a 14K lb trailer that I have, and I'm thinking that the dually would tow it better than my F150. I just need to stay under the magic 26K lb number to avoid needing CDL here in WYO.

How much does a 4X4 dually F350 weigh?

 

Not sure what your truck weighs, you should probably weigh it. If you check the 2013 SD towing/payload guide here-
https://www.ford.com/resources/ford/...superdtypu.pdf

The maximum payload allowed for any 2013 F350 SD w/14000 GVWR is 6360# for a 4x2 DRW crew cab with the 6.2L engine, and 5423# for the 6.7 diesel. You are already way beyond that...I think the post that said you need a bigger truck is accurate

I used to haul a 1000 gallon tank, but it was on a GMC W7, a 26000# GVWR truck...

 

Your payload capacity is on your door post.

 

Also don't forget to add the weight of the transfer pump and tools you'll probably carry to the weight of water and tank. Some states require a tanker endorsement on drivers license for over 500 gal.of liquid. I know it's crazy but some do. Any way to get more money from us farmers.

 

I don't think your going to be able to drop 8600lbs into the bed.

For reference, my 2008 f-350 DRW V-10 4.1 LB rear weights 7000lbs empty. I put 5600lbs of cement stacked on two pallets and had no problems at all. My empty weight plus my payload is below my GVWR.

 

my 2016 f 350 dump truck i haul up to 9000 in the bed with no issue, those axles can handle alot more than mfg states for example the rear axle can handle 13k and front axle can handle 9k, they down grade on purpose. my f 350 dump truck empty is 10k, when i haul i never go over 9k payload, when i get to 9k payload it compress springs about 2 inches, but the truck still feels fine, the tires stay cool nothing feel stressed. even my 1994 f super duty can handle as much but it is not built like these new trucks.
the key is how you haul the load and take your time. i do this day in and day out with no issuses

 

I'm not sure they put that sticker on cab & chassis vehicles.

I have the same truck, just have bed on it.


I come in around 8800 lbs with full tank of fuel/tools and hitch.


For what it is worth that rear axle is a dana super 80. Look it up. It will handle a lot.
