Where did you find a F350 SRW with a GVWR of 15,000#?  I have a 2017 Ram Dually and the GVWR on it is only 14,000# I don't know of any newer 350/3500 duallys with over a 14,000# GVWR little alone a SWR.

They must have started building new SWR 350/3500 trucks with 22.5" semi tires on it to get to that GVWR.  ;D

 Just stay under the truck mfg axle load rating....just like the trailer.

 

GAWR weights for trailer axles do not provide any load capacity reserves. GAWR weights for truck axles do. It's all in the standards. Worthwhile reading if you have the time.

Hint: Get the GAWR figures off your truck's certification label and compare to the truck's GVWR.

Most do.  My 5er had a GVWR of 15,000 pounds and 23% pin weight loaded ready to camp.  Pin weight at GVWR would be about 3400 pounds subtract that from the 15,000 GVWR would leave 11,600 on the axles with two 7,000 pound axles.  So 14,000 pounds subtract 11,600 gives me 2,400 pounds margin if all sides are equal.  If I had zero margin I wouldn't purchase that 5er since it's never even side to side and one side could be 500 pounds more than other side.




Edit --- You not suggesting that you can exceed the GVWR on the 5er and put another 2400 pounds in it and load to axle weights are you?

I'm saying the axles on the trailer are probably not certified at 7000# each. What did the certification label say?

Example: This is how it's done on the certification label. This trailer also had 7000# axles and it's heaver than yours was. It's axles are certified at 6840# each.

You have a 5er that has GVWR of 16400 has a pin weight of 3600 (22%) so 16400 GVWR minus 3600 pin weight equals 12,800 on the axles.  The two axles together are 13,680 so a reserve of 880 pounds. 

My 5er was a Solitude 310GK which have two 7000 pound axles.

This is - in part - what the standard says and is required of the trailer builder. When the trailer's total GAWR weight (value) is added to the trailer manufacturer's recommended hitch weight, the sum must equal or exceed GVWR. Load capacity reserves would be all weight above the sum.

The only axle values that are measurable are the GAWR valuse depicted on the vehicle's certification label.

Brochure weights are nice to know but only certified values count. The vehicle manufacture has the authority/responsibility to set GAWR values that differ from the axle manufactures specs.

My neighbors has a 2017 F250 Lariat and on the CAT scale weight was 7780 wonder why yours is so low?

Maybe because your neighbor actually scaled his truck, and ammo may be stating base weight from the brochure.

Or Ammo  may have a regular cab (not supercrew, not Club Cab) and 2x4 instead of 4x4.

Ammo, dry weight means absolutely nothing...zero, nada, zilch, unless you go camping with an empty trailer, and most people don't!  The pin weight that you posted is also trailer empty pin weight, which again means nothing....unless you go camping with an empty trailer.  Find out the trailer GVWR and multiply THAT number times 20% and you are pretty close to the working or actual pin weight.  Don't forget that the 5ver hitch weight (maybe 175 lbs or so), is also deducted from your available payload capacity, so you will probably find that you don't have anywhere near the payload capacity you thought you did.

Edit.....I just looked up your trailer GVWR....12,560.  That number times 20% = 2512 lbs. Add the hitch in there and you are now at 2700 lbs.  And, if your truck does actually only weigh 6300 lbs ( which is hard to believe unless it's a regular cab, 2 wheel drive) , then you may have approx 1000 lbs left over for other stuff.  Have you scaled your truck?  How do you know the truck weighs 6300 lbs?  Most F250 Crew Cab 4x4s diesels are in the 7600-7800 lb range.....in which case your payload is in the 2200 lb range.
