Hitch weight vs payload

I have anew 2020 Chevy 3500 SRW with the Duramax engine. The payload on the door is 3769 but the hitch weight for gooseneck (and 5th wheel?) is 3180. Does anyone know why this is so much lower than the payload number? We would like to have the Montana high country 383TH, the hitch weight is 3225. So, this is a miss by 45 lbs. how much lighter would you expect the pin weight to be with my 850 lb motorcycle in the back?

Well another 17,000# GVWR 5er I want to tow with a 3500 SRW.
I assume you understand that that Payload number on the door sticker, include everything that is carried in the TV. That is passengers, add-on accessories, Hitch, and anything else carried in the passenger compartment and bed.

The difference between those two numbers is 589#, maybe they are taking into account some averages. then they may be taking into account the rear axle rating. The payload wars are pushing all the limits, TV GVWR's now days are a very high percentage of total axle rating, making it possible to be within payload number and exceed rear axle rating.

You have the truck, take it to the scale ready to tow and weight both axles, take that total and subtract from the listed TV GVWR, that is what you have left of total payload. In addition take the scaled rear axle weight and subtract from the rear axle rating the lesser of those two should be maxim pin weight you can carry.

Please post back GVWR, and both front and rear axle ratings.
