Rear axle weight

I need to know the rear axle weight of my 2021 Ford E-350 25 foot class C Conquest by gulf stream or similar.
If anyone can help with an approximate weight id greatly appreciate it.

I need the rear axle weight to determine which leaf springs to order.
The coach is in Montana and Im in California and must order them now to take up there to install.

I'm looking for someone that has put the back half of their 25 foot class c on a scales or another source.
the whole thing weighs 12,500lbs

Thanks In advance,

Download the CATScale app on your phone, sign up, and drive to your nearest truck stop that has a CATScale (as will be noted in the app).

Other than if your in the northeast, CAT Scales are near by just about anywhere. You really need to know your weights on occasion any way to insure you’ve got the proper air pressure in the tires.

I would also think the specs for the chassis will tell you max rating for front and rear axles, as in GVWR, listed somewhere on the vehicle.

There is the GAWR (Gross Axle Weight Rating), a figure defined by Ford.

Then there is the actual load including the house on the back of the chassis.

The second number is very liquid. Using my own rig built on a 2007 E350 as one example. There is a big increase in weight on the rear axle during a trip versus being back home and empty. These two pictures says it all. The difference on the rear (drive) axle is 1460 pounds.

At Home Without Our Added Contents And No Fresh Water

During A Trip

The 1460 pound difference is primarily influenced by the location of the fresh water tank which is located against the rear wall, right above the rear bumper. The weight of 30 gallons of fresh water is amplified through "leverage".

Or look on the data tag on the driver's door and it will list the rear axle GAWR and order the springs for that weight.

Folks, in his post he says he is far away from the coach at present so suggesting he weigh it or go look at stickers is not possible.
To the OP:
I'm confused why you want to replace the factory springs on such a new rig. Are you trying to raise the GVWR? If there is damage and you are only replacing can't you just go with the published factory spec since you can't access the rig at the moment?

With all the info on the net these days, I thought this would be easy to find. Nope, Gulf Stream's website is lacking in specifications and I wasn't able to come up with much of anything elsewhere.

I did look at the Winnebago site which has a couple of models in the 25' range. Definitely NOT set in stone but they show a GVWR of 12,500 lbs with a rear GAWR of 8,500 lbs on the E350.

You can figure around 9000 lbs and if that's not close enough for you to order springs , then it looks like you will have to make that trip and weigh the rear of that coach ! Surely Ford don't make multiple sets of springs for a E350 !

Do you have a “VIN” for the chassis? If so, can you take that to your local Ford dealership and have them tell you?

Our new ExpeditionVehicle is converted from a 1996 Mack firetruck.
I used only the front frame section including the front axle.

After calling repair shops and our local heavy-truck dismantler, I advertised the rear-axle plus springs and a chunk of the rear frame.
Zero-zero-zero interest.
Accordingly, I hauled the rear-axle to the smelter.
Across the scale, the rear-axle and associated junk weighed about 2,200#.
