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?
Where did the 3180 lb GN/5th wheel number come from ??
The payload sticker is GVWR based number that may overload a trucks RAWR if its used as hitch weight. Like many 4xxx lb sticker numbers on any 350/3500 SRW trucks.
Your 3500 SRW shows to have a 7250 RAWR for 2020. Looking GM weight calculator website shows the high country optioned 2wd crew cab long bed Dmax rear axle weighs in the 3400-3500 lb range. Doing the math shows the rear axle in the bed payload may be around 3700 lbs for a max payload before exceeding a wheel/tire/rear spring pack capacity.
You have the truck so like all truckers load the truck up and drop by the local CAT scales and weigh the trucks front and rear axles separately. That way you know your exact numbers.
