Is this 5th wheel too much for my 3500 SRW?

Payload doesn’t only go in the bed or on the rear axle. Your butt in the driver seat is payload, too. If you have a winch on the front.. that’s payload, too. That big ol 5’er hitch? .. payload.
Right....I get that part, its gotta include it all. But looking at Wileykid's numbers, the payload appears to be related to the 7k rear axle number. As you said though passengers are part of it, and that weight should be distributed between both axles. Just downloaded the CAT Scale app and gonna go weigh my truck this evening. My truck has a GVWR of 11,800 lbs. Maybe the more accurate way of stating what I did above is Payload = 11,800 minus Front Axle Weight minus Rear Axle Weight.

I knew I should have gone to College.

Oooo cat scale app? That sounds fun. I haven’t weighed in a while.

My truck has a GVWR like yours of 11,800 lbs. My sticker payload is 3,750 lbs. I got the 3,600 by subtracting the actual loaded rear axle weight, from the scale, from the 7,000 max axle weight.

The CAT scale app is slick. Had my weight in my email in only a couple of minutes.

11800 is GVWR

Front GAWR is 6000

Rear GAWR is 7000

Payload is GVWR minus base weight...base weight is GVWR minus payload.


Your axle weights add up to 13000. But GVWR is less because the truck tested in steering stoping accelerating and manuvering at the 11800lb GVWR.

Base weight is an empty truck with full fluids.

One of you said payload sticker says 3750.

11800 minus 3750 means your truck has a base weight of 8050lbs.

The long bed trucks get more GVWR. The 2014 to 2018 trucks had the same GVWR for each..and actually the long bed had less payload in those years. But now the long bed has more as with the new frame they can rate theblong beds a higher GVWR

So a short bed Hemi is 11000...long bed is 11400

A short bed Diesel has 11800 a long bed has 12300

They both have the same axle ratings...gas 5500 front and 7000 rear and diesel 6000 front and 7000 rear

As mentioned above...your axles add up to more capacity than GVWR because the axles are only one part of the equation.

This is why your are getting the coincidental payload and rear axle capacity being similar.

You can exceed GVWR...if you are not exceeding either GAWR...just understand that the truck will behave worse than under GVWR.

Diesel trucks have about a 62/38 split front to rear.

Gas trucks have about a 60/40 Split front to rear.

So at 8050 with a diesel front axle should be about 4991 and rear axle about 3059.

One of you said you got an axle weight...can you post the CAT scale slip.

Hope this helped...or as usual it will just stop the conversations lol

Here mine is (loaded for travel).
Steer Axle: 5120
Drive Axle: 3320
Gross Weight: 8440

I will step to the sidelines as this is not my thread.

Legally, payload is GVWR minus the curb weight of the truck. For a SRW Ram 3500 that usually means 12000lbs minus roughly ~8300 lbs (depending on trim level and options).

This is a great conversation. Here is my CAT scale sheet from yesterday. Truck was loaded for camping (wife and I) along with full fuel. Only thing missing is the Anderson hitch.

3500 SRW is 12,300.

8300 isn't even close for a well optioned 3500 CCLB with 50gal tank.

It's uncanny how our trucks are so close, yet mine is CCLB with 50gal tank.

My '21 3500 CC standard box SRW has a sticker payload of 3617 lbs. Engine is 6.7 HO. We're looking at a VanLeigh 320GK. Specs are below. We really like the trailer and it meets many of our wants including a length of 35' or less. On the other side, I want something that tows and handles well as we plan to do some cross country trips and I don't want that feeling of too much trailer for the truck. Wondering if this unit is really DRW territory.

VanLeigh 320GK
  • GVWR : 16,000
  • Dry Weight : 12,400
  • Cargo Carrying : 3,600
  • Width : 101"
  • Height : 12' 11"
  • Length : 34' 11"
  • Hitch Weight : 2,600

Looking at some numbers on a worksheet here, assuming 20% pin weight on maxed out trailer GVWR puts you right at your payload.

It really is. I'm honestly surprised (envious) at the 12.300 GVWR. My rear GAWR is 7,000 lbs. Front is 6,000 lbs. Same on yours?

Sure it's close. My 2016 short bed was ~8100 on the scales. 8300 might be a bit light, but it's not too far off.

Sounds like your truck is 8500 and some change.

my two cents..having owned some of these big 5th wheels, i would strongly recommend a DRW if not for towing capacity/pin weight/gcvr but just the control of the thing, stability, a wider platform in the rear to keep the 5th wheel from overly influencing the truck. i have a DRW and really didnt want one, as a srw is just more manageable day to day, but the drw after having it for a good while is just fine. i have to park sometimes away from where the SRW would slide into a parking spot at home depot or something like that. but when loaded with the trailer, there is a very notable difference. i think my keystone fuzion is like 17500 total, 14k empty 3500 cargo.
those HO motors are monsters. on the rams they give you like 29 tto 34k total towing and big pin weights in the 5000lb range if not more.
i didnt really want a drw but i went that way to not have other aggravations. i have a wrangler i can use for easy breezy fun drives.
have fun.

As mentioned earlier, both Brutal and I basically have identical trucks. He has 3500 Limited and I have 3500 Limited Longhorn. Both are SRW. His is long box, and mine is short box. Both have same drive trains. He gets a GVWR of 12,300 and I get GVWR of 11,800. In theory my truck should be somewhat lighter due to shorter box, frame, etc. What parameter allows the long box to get an additional 500 lbs of GVWR weight?
