So can anyone explain this to me? I have a 2016 F350 6.7 4x4, 3.55 differential, 11200 GVWR Package, Crew Cab, 172" wheelbase. So when I look up specs from Ford, it says that my configuration has a maximum payload of 4,060 lbs. But what I don't understand is any other GVWR package has less payload even though everything else is the same? For instance,

11,000 GVWR = 3,890 Maximum Payload (I would expect this to be lower since the GVWR is lower)

all of these are higher GVWR but LOWER Maximum payload:
11,300 GVWR = 3,440 Maximum Payload
11,400 GVWR = 3,510 Maximum Payload
11,500 GVWR = 3,610 Maximum Payload

Am I just not understanding what these numbers are telling me? I would expect the same configuration with a higher GVWR rating would have a higher maximum payload, but it doesn't?

 

My guess is that the higher the gross rating goes, the more the truck weighs. So add weight to the vehicle, gross goes up with it to compensate.

Then, to round it out, the addition of each weight rating is subtracted from the payload available.

I know that when all those rating are compared to each other it doesn't follow exactly. Maybe it's a percentage thing. I dunno.

Just guessing.

 

What makes the truck weigh more? These are all configured with the same engine, same 4x4, same rear end, same wheel-base, etc.

 

3 different GVWRs are offered in all 2016 F350 configurations, not to mention all the other GVWRs that are applicable to certain configurations, along with their corresponding payload rating. I would guess a few of those ratings are for a specific trim level. For example, your XL doesn't come with heavy 10 way adjustable, heated/cooled, leather seats. Some heavier trim levels will be configured like yours, and need a higher GVWR to have a competitive payload, however, they still end up with a slightly lower payload than yours. I noticed a lot of this while searching for my F350. The literature never told the whole story, I had to open doors and look at door jamb stickers to find the right payload for my needs.

 

A crew cab weighs more than club cab, that weighs more than than regular cab. 4/4 Weighs more than 4x2 drive. Long bed weighs more than short bed. Dually weighs more tha SRW.

With very few exceptions, weight of truck goes up and payload is reduced by the weight of every option that you add beyond base model.

 

Ahhhh! This is the only thing I have heard so far that makes any sense at all.

 

And, on top of everything else, the payload sticker on the door is usually a bit higher than reality. Mine is 3568# but when I weighed my truck with my 5th wheel hitch in, a full tank of fuel, and my family aboard, I already weighed 8550#. Subtract that from my GVWR of 11.5k and I have just under 3k of payload capacity, not 3568...

 

to know your true numbers you need to weight it empty. Then the GVWR minus your actuals..per axle can be determined.

 

But I don't have a 5th wheel yet, I'm trying to figure out what the truck can handle.

 

As I said above, weigh the truck and subtract that weight from the GVWR you have your true payload.

 

weight it empty to see what you have for room.


Then you can select a 5er within the specs of your available (actual) payload and your GCVWR.


Remember that a 5th wheel will have a published dry hitch weight (which is payload for the truck). Ignore the dry hitch weight and look at the data plate.


GVW on the trailer data plate and then 20% of that will be close at what your pin weight will be. Based upon that you will know if you are ok or need to look for something else.

 

My opinion, your truck can handle anything they make with 2 axles and the smaller triple axle ones.

 

You think it would handle this?

Unfortunately not. The dry pin weight is just way to high for a SRW. Take a look at my brand, XLR. Their pin weights are much lighter than the competition due to axle placement. Mine, despite weighing over 19k loaded had a pin weight around 2700#. The Thunderbolt's are more loaded with options and the Nitro line is more value oriented. Both have decent pin weights for a SRW.

That one is a bit much for a SRW. That will overload your rear axle.


That us DRW territory.
