Ford's payload capacity confusion

[azjeffh]

Just ordered a new 5er and looking for a truck to pull it (21K GVWR).

According to Ford's website, I should be able to get a 2016 F350 4X4 dually diesel that has a 14K GVWR with a 6460 payload capacity. The problem is when I went to look at one last week the label on the door stated ~5400 lbs payload. To me that doesn't make much sense since I doubt the vehicle's unladen weight is 8600 lbs. Shouldn't GVWR-CCC=unladen? I did verify the vehicle did indeed have a 14K GVWR placard. The GCWR is 35K which should be well within the limits of the combo.

In addition I'm trying to decide between the 3.73 and the 4.30 rear end. I understand the 4.30 has a 3K greater towing capacity (26.5K vs 23.5K) but will likely burn more fuel. I really don't understand the other advantages of the 4.30.

I had considered the F450 but oddly enough the payload is stated at only 5300 lbs which is really confusing to me.

We plan to full time and travel the US so I'd like to get this right the first time.

I guess it is to make sure he Mor/Ryde IS is working.

When I talk to them about adding the third axle I will ask them if they found a Bilstein shock to fit the IS system. If so I will have them install 6 of them.

Cummins 12V98, Had my risers done at MorRyde this past June. They are pretty good people. You get to stay inside overnight when they tear you apart two day job. Make sure you have them measure your height when they complete the job. If you need any warranty work stop by DRV they do a good job with the repairs. Might even fix things you don't know are broke. Been there twice. Just call and make an appointment. Good Luck. Last thing a lot of folks don't have any idea how heavy these things are. But they handle so nice behind them Rams.

Thanks for that info. I was planning to go back to MorRyde and DRV in the Spring to have some warranty work done. The RV was delivered to us in May so I want to get back there before the one year is up. I am sure I will get the third axle added at that time since it has to be completely torn apart to add the riser. I will have DRV add the 3 axle fender skirt before going to MorRyde.

within front/rear axle ratings and combined tow ratings

DRV is full of Barbara Streisand with their numbers!!!

At 23K what size axles are on that beast? Even with 5k on the truck you have 18k on the axles.

MorRyde IS axles. The axle weight is 17,500#. I know the IS is no problem with that weight and the GY H tires still have more capacity left at 4,800# per tire = 19,200#.

I am thinking about adding a third axle when I have the 2" riser added at the MorRyde factory. It would be a pretty simple add at that point since the axles have to be removed for the 2" riser.

mine weighs 5K over the 18K they "SAY" it weighed at the factory. I wish I could have weighed it when taking delivery. NO WAY even with the 6500 gen I have added 5K!!!

[momentum_rv]

The numbers just don't jive. Even at 16k on the axles (2 8k axles) that leaves 7k on the pin... sumpthin' wrong with this picture.

[hone_eagle]

Guessing 8000# axles the rest on the truck/pin?

Gonna say triple 7K axles?

I don't think it is...

You'll be fine with a 350 DRW with the 14K package. Your trailer is slightly smaller and lighter than mine and mine does fine.

I was releaved to have seen your post. Your have a very nice and expensive fifer. After googling and seeing the hitch weight of 3000 lbs. Im thinking the GVW is less then 30000 lbs.

BTW, this is not my rig. I thought it was the OPs.
