3/4 ton truck towing capacity

This topic has probably been discussed to death, but I remain confused. The owner's manual of my 2017 Silverado 4wd, Duramax, crew cab, short box, lists the maximum trailer towing capacity at 13,400 lbs. Not sure if that includes 5th wheels, but suspect so. My logic is that even though 5th wheels and travel trailers are of different designs and hitching methods, they are both trailers. However, the same manual lists the GCWR (which adds the truck into the calculation) at 23,500 lbs. My truck scales - without the 5th wheel attached - at approx 8100 lbs. Subtracting that from the GCWR indicates that I can pull a 17,200 lb trailer. Which is right, or am I missing something? Thanks!

I'd guess that the rear frame bumper hitch rates the 13,400 figure. 5th wheel takes you to the 17,200 figure.

Sorry, not much help.

I would ditch the manual info and use the info off of your trucks door for your towing ratings. Those numbers are the real numbers for YOUR truck. The manual is a general rule of thumb.

Sadly they are only part of the equasion. If you were crazy enough to hook onto a 17,000 pound fiver you would be dropping around 3500 pounds directly over the rear axle. Effectively turning your 10,000 GVWR truck into a 11,600 pound pile of scary. What is your trucks RAWR? And what is its scaled ready to travel rear axle weight?

Payload is the number you need to determine the maximum trailer you can carry. Check your door jam for a yellow sticker. Mine from my 2012 2500 Duramax is shown below. My max payload, which includes all passengers, gear, bed cover, hitch weight, and either tounge weight if a travel trailer or pin weight on a fifth wheel cannot exceed 2431 lbs. Using that information is going to dictate what I can pull. In general a fifth wheel carries 20% of the total trailer weight while a travel trailer is around 10%.

I hope this helps!

"Maximum towing capacity" is only that...a maximum. It is the MAXIMUM that can be towed IF all other ratings are not exceeded. Being within some ratings but over another is a no go.

Beware not to exceed any of the ratings. (Cargo Carrying Capacity is easily overlooked and often inadvertently exceeded.)

A competent tech at a hitch store or trailer dealership can be a good resource. Posting on this site is another good resource.

Fivers carry around 20% of their total weight as pin weight, not 12%

There is no way a 2500/F250 is rated for 17.5K, I have a 14 RAM 3500 SRW and it is rated for 17.5K (CCC of 4450), according to the GM website your truck is rated for somewhere around 13,500 towing, depending on the options, now the CCC is totally different, you will hit that well before you reach the max towing. The figures I put in the post are for 5th wheel and gooseneck, TTs are actually less. The CCC for most 2500/F250 are somewhere are 2500 give or take a few hundred pounds depending on the options.


Here is the link I looked at: https://www.gmfleet.com/content/dam/...wing-guide.pdf

My 37 ft 5th wheel has an emty pin weight of 1855 lbs. After loaded the pin weight was 3750 lbs. So I was 1200 plus lbs over my cargo capacity of my 3/4 ton before I added fuel, people and cargo. It adds up quick. I now have a 3500 DRW I still had 1000lbs. Left on the ccc of the 5th wheel.
