Calculating Payload and other max weights - Am I missing anything?

I have a 2016 GMC Sierra Denali 3500 SRW. I am towing a 2018 Solitude 301 GK. The truck (loaded and ready for camping with DW and dogs) drive axle is 3700. Total truck weight loaded is 8640. Truck and trailer (fully loaded) rear axle fully loaded is 6400. Trailer axle fully loaded is 10700. Total truck and rig is 22120. Based on my math, pin weight is 2700. Max payload on my sticker is 3729. To me that means I have 1029 lbs before my payload is exceeded.

Can anyone confirm my math and let me know if I am missing anything? GVWR is 11500, and GCWR is 25100. Im just trying to figure out how much more weight before I exceed any of the max weights.

TIA

Chris

You need to post the FAWR and RAWR from your door sticker to get the correct amount you could add for weight , and where the weight needs to go .

Remember not all the total payload is available at the rear axle; and it's not always possible to put weight in the truck so it loads on the front axle.

GCVW 22,129 minus trailer axle 10,700==== 11,420 truck GVW with pin weight

Truck Rear Axle w/o trailer 3700 and with trailer 6400 ---difference of 2700
Truck GVW w/o trailer 8640 Plus 2700 pin weight===11,340
So it appears you also are adding 90 to Front axle ===2790 total pin weight
** my hitch set up adds 150 to front axle

Sticker Payload 3729 minus total pin 2790 === 939 below Payload
GVWR 11,500 minus total 11,420 ===80 under GVWR
GCVWR 25,100 minus truck/trailer combo 22,120 ===2980 under
GCVWR

And I take it you are Under the trucks RAWR

Looks like good to go

If Old-Biscuit's calculations are correct , and they usually are , the 80 # under GVWR , is your answer .
Even re-reading the numbers I'm having trouble with the amount of available payload and RAWeight compared to the RAWR, and how close you're coming to the GVWR. Time for me to dig out my calculator.

Just to be clear, you only have 80# before you exceed GVWR when loaded. That is the TV loaded weight of 11,420# from the 11,500# GVWR.


The listed payload 3,729# everything added to the truck since it left the factory, passengers, driver over 150#, hitch, and anything else carried in the truck.

Fully understand. We were in between campgrounds when everything was weighed, so we were around or at our max payload for the truck and camper. Just wanting to make sure I hadn't missed anything with my calculations that would put us over at that point.

Thanks

I just upgraded from a 2016 GMC crew 4x4 duramax. My rear axle was over weight by 700~800 lbs with a our 16,800lb (scaled ) 5th wheel behind us. If you keep your 5th wheel weights under about 15,000lbs you will be about max on pinweight and near max combine. Front axle rating never come even close , the rear axle will be at 7050 before you reach the max two rating with a RV . I will say that my 2020 DRW truck is much easier to drive , the back of the truck isn't steered by the trailer weight in corners. pulls hills better due to more power and more gears on the trans. It runs a less RPM on steep hills and has much more TQ at a lower RPM. I got 42K for my truck with 100,000 miles on it selling out right then bought new for $75k
