OP - what's the vehicle in question?
Relatively rare for OEMs to specify tongue limits for hitches they didn't supply.
With an aftermarket hitch, tongue weight is just (badly placed) payload. As long as you don't go over rear GAWR, then I don't see why you're limited.
It is a 2017 Hyundai Santa Fe AWD. All models come equipped with a towing package which includes tran cooler and wiring to bumper, but no hitch. Only after after market hitches are available, and the CURT one specific for the vehicle (bolts to factory frame holes and hitch aligns through cutout in bumper) is weighted for 900lbs tongue. If I recall correctly the door sticker states it has around 1300lbs payload. I did do a CAT scale measurement with vehicle loaded and it came in 975lbs under GAWR.
