I'll just leave this here for all the 500/5000 folks...
Note this is from a 2019 GM truck owners manual, so ymmv...
Vehicle Series Hitch Type
Maximum Tongue
Weight
1500 Weight-Carrying or
Weight-Distributing
567 kg (1,250 lb)
2500/3500
Standard Box

2500/

PS, the hitches on a 2500 and 3500 from the factory are the same, 1500tw vs 2000tw is likely due to GVWR restrictions as this is for gassers which didn't get the GM 2500 "bump" in gvwr.
Or the cliffs notes. 500lbs tw is NOWHERE near needing a wdh to save the hitch.
Not even on a newer half ton.
PPS, 5000lbs is the bumper ball limit.
